 So, hello, so who are you? Hi, I'm Vahid Akhavan. I am one of the development engineers at Nova Centrics I have been with the company for Around three years now a little bit more than three years and it's a very exciting place to be working actually I have been in many different situations previously Nova Centrics we get to interact with many different customers and it's It's actually a very big thrill to be here in Berlin to be representing Were you working with printer electronic stuff before? I was I was actually concentrating on six photovoltaics for social process both solar cells and the six photovoltaics business actually requires a process called sound station and In the sound station process what we do is we place Copper indium gallium films in a selenium rich atmosphere and we annealed that at 500 degrees or higher temperatures and We can form a Copper indium gallium selenite not a crystal structure that can be used as absorbent material for photovoltaics, so what I was doing as a graduate student. I was working to to create copper indium gallium selenite crystals in a solution and then I was a spray depositing the solution onto the back contact and then Making a device out of that. So that was a few years ago that did ship commercially We did do some commercial stuff. Unfortunately that that is still a development project much And has not really taken off So comparatively, what's going on here at Nova Centrics? What what kind of stuff is happening? What are you working on? So at Nova Centrics we work mainly on Mainly on print electronics, obviously that's why we're here What what the main goals of Nova Centrics is is to deliver the tools that can be That can be used to generate the next generation of devices in the electronics business So we deliver nano crystalline-based inks that can be printed into conductive circuitry and then we deliver Photonic curing equipment, which are the state-of-the-art flash lamp systems that that use quite a few added features to a flash lamp system to enable Uniform pulse control to enable fast processing rate through water cooling of the flash heads that enable control of the Full production through a user interface and but also enable a Simulation of the temperature profile within the short processing windows that we have Um We have established with photonic curing So is it a fun job for the engineers at the Nova Centrics to make all this stuff? Absolutely. So what happens every day? So at Nova Centrics, it's it's No two days are alike. I have been there for a little bit more than three years as I said and we have been Expanding into very new territories that I never thought possible. We have been working on displays on battery on storage devices on on textiles on An unvariety of different techniques and all of these things were Dream or a vision a few years ago, but they are slowly taking shape into reality And we we will we are expanding and we put our photonic curing equipments are now Incorporated in actual production lines where Where this is something very new for us. So it's kind of Interesting and what what's possible with printer electronics? Is it is it kind of like a printed PCB on a Plastic and stuff and then but it's a low resolution compared to Other kinds of PCBs. What's possible? What's going to happen? I mean PCBs is one one Venue that's very interesting. I mean The ability to print Circuit board instead of having to manufacture a circuit board and an environment is Is amazing but that in itself Will not displace the At its current stage will not displace the conventional PCB manufacturing Conventional PCB manufacturing has been for a long around for a long time and people actually are very entrenched in that In that business. So I want to replace that but there are there are many new Venues at which we can apply these concepts that open up Open up opportunities that don't actually exist today, and I think that's where Print electronics can come into play. So for example textiles is a great example of this is happening. So this is uh Is a real it's kind of like it can be worn. It can be worn. There's a battery in there and then so this This prototype is does I can't wear it I just don't want to wear it because I will make it smell. Yeah, and then we have to wash it. But um, this prototype trambi is operating on a kind of a hybrid system or that We have printed conductive silver paths that that are um That are screen printed out of silver materials that novacentrics manufacturers and but the the leds the battery pack that the actual connectors the control board are all conventionally available Structures this Demonstration is used to demonstrate the versatility of and the ability to actually print Conductive patterns on clothing and still achieve very good and pasty on these patterns on these circuits So how do you do that? That's a different machine, right? So, I mean this is a screen printed sample It does not necessarily use the photonic curing equipment Even though we would like to use the photonic curing equipment for various Aspects of what we would deliver to the Garment industry. It is not a necessity for the government See that at novacentrics we work on so many variety of different techniques to actually Process the materials one of them being the photonic curing equipment So, um the printed electronics is pretty cool, uh Area area right absolutely So But how how soon is it everywhere in the world? Is it already a little bit? So printed electronics Is expanding rapidly actually we are getting into into the Customer world through our RFID manufacturing through manufacturing of Items that because of proprietary nature of these items, I can't discuss them in full detail here, but these things will be Ubiquitous in every day life and we will no longer believe in them as printed electronics We will believe in them as everyday items. So they will not be a distinction between The real world and our world we are the real world But the consumers are going to be a little bit impressed when they see this kind of stuff arrive around the world and they'll be like, uh Overwhelmed or they'll be like, ah, it's just okay. This this technology For because printed electronics world is being slowly incorporated into into the conventional electronics world what we are experiencing is that Consumers no longer can tell the difference whether an item was printed or an item was uh edged or an item was stamped these are all kind of being meshed together into a Into a unison that that the that the Consumer will no longer be able to distinguish these and if the consumer is no longer just being able to distinguish this I think that's the highest honor that the printed electronics world can can achieve So you said etched or stamped are those the conventional ways Well, those are the conventional ways for making for example RFID tag antennas is either Etched copper or stamped aluminum are Added additive technology by depositing the middle on ink and processing with the pulse force system Is a unique operation that doesn't require either etching or stamping So you said you were working in displays and in power batteries Yes, so amazing and awesome. They are amazing and awesome. Absolutely. There is there's a lot of things happening Unfortunately, we only have a limited bandwidth to work on specific items, but we believe we can work with quite a lot of Experience partners that are experienced in these fields that are helping us achieve Goals that are being set in the in the displays or in the in the storage devices or in Other types of electronic manufacturing So has it been at the at the show the printer at the show is great We have had two very productive busy days In our past and we are hoping that the leads we have generated from this show will pan out to Real partners and real customers
