 Ευχαριστώ πολύ. Στον χρόνο εξαγνήσαμε τα δημοστάσματα για αγριβολταγές, για να παίρνουμε μια αγριβολταγή σολουσία για γρήν χαούς, και οπηθέσεις, για να μπορείτε να γίνετε πόρυ, και να δημιουργήσετε κρόπες στις τρόπες. Αυτό είναι το δημοστάσμα μας, το πιο γρήν χαούς. Μπορείτε να δούμε εκεί. Λοιπόν, αυτό είναι κάτι στο Θεσσαλονίκη. Θα την δούμε πέρα σε ένα από τα αυτά. Θα τον δούμε. We will take a closer look into that so we can walk inside. You can see it's a bigger installation we've already grown tomatoes. You see, the tomatoes are red. We also have- And this can help to light them 24 hrs a day, or you bring more light. Exactly. When it's darker. With organic photovoltaics we are able to manipulate how much irradiation and heat goes actually on the plants themselves, themselves. Οι χωρίς δεν παράγουν σχεδιακές, και έχουν ένα βασίδιο γιλόματος από 30% για τα μάτια. Δεν είναι το κένι. Και τι είναι αυτό εδώ. Αυτό είναι το σωστό βιντο, που έχουμε εμπληκτικά σωστό βιντοκλή, στο σωστό βιντοκλή. Αυτό είναι καλύτερο για να δημιουργήσουμε τις σωστό βιντοκλή, όπου οι φωτοβολογές μπορούν να είναι τελειώσεις σε διάφορες σωστό βιντοκλής, αλλά σε αυτό το μόνο που εμφληκθεί, θέλουμε ότι είναι εκς σεγράψεις και θα έχετε σημανό στην κατάρρυση. Και έχετε δίμως εδώ, από αυτές τις σωστό βιντοκλή. Οι δίμ secular υπάρχει εκεί. Θερνημούμε εκεί. Ας δούμε. Αυτό είναι το δίμιο της κατάρρυσης, σ處 αυτό παράδειγμα, η άγιση είναι η ελουμιούλη στο σωστό βιντοκλή, και οι φωτοφολτατικές πάνελες είναι αντιμετωπισμένοι inside the triplex glass. So everything glued is protected from the elements and is able to generate renewable energy. Is it transparent? Yes, it's semi-transparent. You can see it's above 35% transparency. You can see the kind that you can see. Alright, so it's important to keep the shade in the buildings when it's very hot? Of course, if it gets very hot and buildings, you know, people are not very comfortable in high heat and high sun, okay? Behind the glass is actually very cool and this is the next generation of building integrated bundles. Can you see it over here? Okay, this is more uniform in shape and color, there are no stripes and it's actually a higher transparency. Are you able to do mass production? Yes, yes, yes. How is the series extending this to mass production? We are able to manufacture it in a roll-droll format, okay? So we use a very big roll-droll machine to produce this in high volumes and we are able to address the market needs. So this is a panel, okay? This is our next generation of building integrated bundles. Can I buy this and put it on my house? Yes, you can, you can contact us and you can buy it directly from us. If I need 20 meters, it's fair. Yes, you can buy it for 20 meters, maybe more. How about, is it going to survive the snow? It can, it can. We already integrate this in polycarbonate sheets or even glass to protect them and give them the ability to survive in the harshest winter. And it's going to last 40 years? What's the life expectancy? Not even glass will last 40 years. We are around and maybe above 10 years in lifetime. And then I just put a new one, right? You just put a new one. And the next gen in 10 years will maybe have more... Maybe triple the efficiency and double the lifetime. Nice. And it will be easy to upgrade? This is very easy to upgrade. Actually it's very easy to install and put it in many different applications. So it's very easy to remove it, as it is to install it, of course. We can remove it and put a new one, what do you want? Is it cheaper than conventional? No, we cannot compare it to conventional silicon technology. This is much more mature in terms of efficiency and technology development. This is the state of the art in photovoltaics. So it's high efficiency? It has higher efficiency for organic module, okay? Are you able to say that eventually it will be the highest efficiency or compared to all the other technologies? It's very difficult to compare technologies between themselves. We hope we have a lot more applications for this type of modules and hopefully one day we can match the silicon technology performance. Nice. Yes. And I heard that you even have a crazy setup outside in the... Yeah, we can go check it out. You can check it out? Yeah. Nice. All right. And you have a bunch more stuff at the booth. But maybe we'll check back during this week, right? Let me take one of these panels with me. This is the same type of panels that are integrated in the parking itself. Okay? We'll see more without side. Let's go. Okay. So has it been busy two years? It's actually, yes. Three years since we last met. Since we last met? Yes, it was 2020. Since your last time here. 2019, last time. Yes. Yes, exactly. Right now it's more people here, more people on the live event. Okay? Some people actually on the remote. But we are very pleased with the results this year. Let me put my sunglasses on. Great. And we can walk outside. It's very hot outside. Cool. Day is around 36. It's the best place in Europe to work on solar technology. Yeah. It's very good. We have one of the highest... The radiation here in Europe. So we can understand this. It's a very good place to develop solar projects. All right. And everybody in the chat, let me know if the quality is good. And ask questions we can ask. Let me know in the chat. So this is the parking installation that we have this year. We can see this is the type of format of panels that we use. So we take these panels, we prepare them with cables and diodes and stuff like that. We glue them on the polycarbonate sheets to protect them. It's glued from the inside to protect them from the elements. I'll say heavy snow or maybe hail. And then we connect them in series and in parallel to form electrical strings. And all this energy, all the energy that's produced here is stored in battery. This type, in this case, is a small battery type. But on a real type scenario we have a lot bigger battery. So we can manipulate the stored energy as we like. So we can use it for illumination, for, let's say, camera setups, closed circuit TV, or even Wi-Fi broadband services and stuff like that. The biggest challenge is how we can supplement the charge for electric vehicles. So for that reason we can pair an appropriate electrical charger that can use renewable energy produced here on the site to actually supplement the charge for electric vehicles. So this roof is going to help charge the car? Yes, exactly. How much of the charging is going to happen through the solar roof? It depends on the car? Yes, it very much depends on the situation and the car itself. But it can supplement very nicely the charge of the car. And at the same time have a very nice shade where it's cooler here underneath. The whole parking should be like this. Eventually the whole parking should be like this. Here, under the photovoltaics, maybe it's 10° cooler that's on the sun. It's important to be cooler. You save energy cooling the car later, because if it gets too hot. This is a passive advantage. Because not so much radiation goes through the panels. The panels have the added benefit of cutting 100% of UV radiation. So no UV radiation reaches the car and people underneath the panels. So this will help actually not put too much heat stress on the car. Nice. So what's the price for these 20 m or something like that? You cannot say, huh? No, I cannot say. The price is very much depends on the specific situation. It'd be nice if people could cover their roofs in their houses for affordable price. And just connect, save some money and energy. This is our main goal, to provide sustainable electricity. Because we are able to provide this in high volumes. And now we are trying even more to increase the efficiency and power output. And also the lifetime. To be able to implement this kind of technology in many different formats. So building integrated photovoltaics, Agrivoltaics with OPV, Electromobility applications and so much more. But the question is, when do politicians jump in or companies and place a big order? Yeah, this is already happening. This is a technology that we need the public to know more about. That's why we do all these events and we participate in so many exhibitions around the world. To educate the public and actually get the big investors, get their attractor interest and actually make them develop projects with this kind of technology. There's one question. Can these be put on top of electric car roofs to charge them while you drive? Yes, we have done projects with a large car manufacturer here in Europe. That was around 2016. These were some preliminary projects. The technology is very much more mature nowadays. And actually we are planning to do even bigger installations on cars and other types of trucks, of transport vehicles. How good does this work in cloudy countries compared to other solar panels? Yeah, compared to other panels it works very good. I think maybe it can lose around 30% of its efficiency, but it can work even on cloudy weather. There is no problem for that. Are you able to say some numbers in terms of efficiency? Yes, we are looking above 6% for the fully printed panel. For this type of fully printed panel. 6% Yes, it's above 6% actually. Last year it was around 5%. This year we are looking above 6%. And we are more than 7.5% in the lab scale. So the small scale that's already in research and development. How do you get to more and more percent? What is the trick? The trick is to improve our printing process, the improvement in materials and our know-how actually on how to print them and increase the yield of production and the power efficiency of the photovoltaic panels. So is it kind of like the materials you use, the mix? It's a mix of materials? Are you thinking of perovskite? Currently no, currently no. We do not have perovskite under consideration for a large scale format. This organics is the largest scale that we use currently. But the efficiency and the improvement in power output is a mix of better materials and better process. So we are able to produce a better panel, a better OPV. Nice. Do you have this on your house? I'm developing a project actually, yes. This is under development. Yeah, I really want to see affordable solar and easy to just place an order online to get a little roll. And maybe you could even install it yourself and not be afraid of insurances, regulation. Just put it on your roof, plug it in somewhere. That would be maybe the next step. If we develop some kits, DIY kits so anyone could just place an order and install it in windows, let's say sunshades, or ports like this one. Lot of different applications. I'm just going to say number but I don't know. It'd be nice, 1000, couple thousand, I don't know how much you need for this size. This is more than a couple thousand euros because you have to consider the different materials, the parking, the development side itself, the OPV installation. Maybe 5000. Maybe more, maybe double that. We're always trying to have a better performing product with lowering the cost at the same time. If you buy the panels and do it yourself, install it yourself, different price, right? Yeah, maybe you can save some bucks but okay. The main cost here is the photovoltaic panel itself, not the installation cost. So that's why we're driving, we're trying to drive the cost down for the panel itself. EU, the EU, Greece, everybody should put billions into this. They should be like, hey, this is a top priority. Let's get some European solar technology out there. And actually green technologies is in the core of EU policy, European policy, sustainable technologies for solar and more especially RES. So yes, the policy is there and now we need even bigger investments for the technology and the actual projects themselves. Nice. So that's what the conference is for, right? Yeah. You're meeting with the regulators, you're meeting with politicians, you're meeting professors. Exactly. You're meeting startups. Exactly. This is a very large multi-event where scientists, engineers, policymakers, everyone comes here to see the new technologies, what are the latest developments in solar and especially OPV. So a lot of brainstorming, a lot of ideas getting developed right here right now. So let's hope this year we get more and more ideas, better ideas and actually we have a very positive impact. Can these be used on their own, not needing a battery? You can use it directly, but it's best to have a battery. So you can produce electricity around maybe 10 to 12 hours a day, you can store it and then you can use it later. Alright. The battery is also a cost to consider. It is a cost, yes, of course. A good battery, you need a big... A whole project? Yes. For the whole project, the cost of batteries maybe 30 to 40% or even more. Alright. And maybe we can go back to your booth? Yes, let's go after our booth. And at the back also you have some more demos. Yes, let's go. Is it fun to see people? Yeah, after all these years, with COVID situation and stuff like that, it's very good to see people, discuss with people because there's no substitute for actual conversation. Okay, so... There's one question. So this solar is better than wind power? I cannot say that it's better than wind power. It's supplementary, okay? Wind power is a completely different thing. All these technologies are all renewable energy, but nothing is better than the other, okay? We need everything. Exactly. Let's go and look at your insulation over there. It's like different kind of use cases, right? Yeah, we have different kind of use cases for organic panel. Let's see. This is a retractable pergola. Let me demonstrate. We have implemented the photovoltaics in the covering material. Because they are very lightweight and flexible, so they can be degraded anywhere. You can retract it. There is an electrical mechanism that is also able to operate with OPV power, okay? And you can actually set it up to cover a very big area. This is a small one that's for demonstrative purposes, but you get the idea, okay? OPV panels are installed on the covering material, and at the same time provide enough shade for people to be comfortable underneath. So no UV actually reaches people staying downside. And also you can generate electricity to power up electronics, charge your devices for lighting and anything else. Start with moving to the next one. This is our pergola bed, specifically made for tourism here in Greece. Here in Greece tourism is a very big thing, okay? So we try to find different applications in the specific niche market that requires new projects that can have some added value and added benefit for the customer. So in that case we have implemented the OPVs on the roof, again on the roof of the pergola, the wooden pergola. And we can operate a small refrigerator down here. And also people are able to itself the devices through dedicated USB ports. And there is actually a 12-volt port to operate different other things. Nice. So it's like really for the beach. Yeah, this is for the beach, specifically for this kind of setup, yes. Exactly. And right here we have our solar bus station. This is for projects that we have developed here with the municipality here in Thosaloniki. In this type of setup, the photovoltaics are embedded in two sets of polycarbonate so they are fully protected against the snow, rain, hail, even extreme heat. And we can produce enough electricity to power up the advertising port in this LED, in this scenario. And actually there are not two but four USB charging ports to charge your mobile devices, let's say phones, smartwatches. When you wait for the bus, you can just plug it in and have a quick charge. And all the electronics, this is not setup completely right now, all the electronics are embedded in this system. So it's all in one system. And it can be remote installed in many different scenarios. You don't need to be tied to the grid. You can just have a battery and photovoltaics and you can power up all your setup. And there is also an LED stripe right here that is used for nighttime illumination. Nice. So it's just a question of replacing order for hundreds of these and all the different local governments all over the world. So for the smaller to the larger project the developer has to come to us. We can develop the whole project or bring more people together, more companies together to build the bus station, we build the photovoltaics, we install it and then we deliver it to the client. Nice. There's one question here. Solarpar came a long way since my solar calculator. We had solar in his calculator in the 80s. Yeah, this was a very good design. Huge advancement. This is over 30 years or even more of development. This is the third generation. So we have gone through third generation, second generation of thin films. This is the third generation, fully printed, organic solar cells. Nice. Should we walk back to your booth? Yes. There's even more. So we're looking at those cool curses. What's the brand? We can't say on camera. But you can work with them. They contact you? We can. Not them specifically, but we have them contacts with developers. It's actually huge to have a brand name on top of that. The main idea behind this is how you can use a system that generates electricity in a portable format. So this is not specifically wearable, but you can see it's very lightweight. All electronics are implemented inside the bag. And there are charging stations so you can plug in your phone to charge. Okay? And also light for nighttime illumination. In this type of human space, this is one demonstrator. This is the other case of our setup where there is a dedicated USB port here to charge your device. And actually there are lights that you can see that you can use for signal purposes. And the full organic solar cell is implemented very nicely on the front of the bag. We have been contacted by several motorcyclists and they saw, for flexible lighting, they saw the advantage to use this type of technology in the actual in the actual jackets. So we have incorporated a film strip, a very lightweight, this is less than a hundred, less than a hundred, of a millimeter in width. It is incorporated very nice on the back of the jacket and this can illuminate in the night giving more an optical signal. Okay? Signal of the other drivers that there is an actual person on the motorbike. Okay? And we also, we have done the same work on helmets. So, all this flexible lighting is incorporated in the cell of the helmet and it's able to illuminate. Okay? You can see we can operate it. So you do flexible solar and flexible lighting. OLED. We do flexible solar, flexible lightning, OLED, electro luminescence. We also do flexible sensors, flexible antennas, RFIDs and stuff like that. We print, we can print a lot of different things. I got a couple questions in the chat. Yeah, let's see. What's the cost per square meter? Right now, it's more or less 1000 euros per square meter. For the solar? For the solar, panels, installation, cabling and everything including. All right. And here, how much power does the solar output, is it 6% you're talking about? This is a 6% efficiency. It's around 25 watts per square meter. Of install capacity, yes. Can install in other country to produce the solution. Yes. You can work with every country. We can work with any other country, yes. We work with a lot of European Union countries. We work with USA, different countries. So everything is possible here, yes. Nice. Let's continue. You were talking about this helmet. So that was more about the display. No solar? No, there is no solar here. We are trying to do it for a later demonstration. But the main case here for this type of applications is how we can use flexible lighting that we could use in this type of installations. And the last one that I'm going to show you is the jacket that incorporates flexible lighting. Let's see. This is another one of these safety jackets. Okay. So in this instance we can provide a signal, an optical signal to say that someone is here. Okay. There is a presence of a human here. Okay. You can see everything is incorporated inside. It's very lightweight. So anyone can carry it with them. So it's about safety. Everything about safety, yes. Even with the helmet and the jacket, the motorcycle jacket, it's all about safety. You know, you need that extra optical signal especially when the night conditions result in enough light. Anything extra can benefit. What's the partnership that you do or do you do it yourself, the whole role-to-hole manufacturing? Mm-hmm. We have a very strong collaboration with Lab for Thin Film here in Thessaloniki, the LTFN Lab from the Aristotle University of Thessaloniki. We exchange a lot of knowledge. Okay. A lot of R&D, so research and development. And we produce anything. Everything here is produced in a role-to-role format. Nice. So it's going to be a busy week. Yes, a busy week. A lot of very interesting talks and topics here. A lot of very interesting people. Some new, some... Okay, we have met again. But it's great for networking and meeting new people always.
