 The world around us is getting smarter. We need our energy generation to get smarter too. Soon our lives will be controlled by 75 billion devices by 2030. Those devices are internet of things. Wireless devices, sensors connected to everything possible in every room. They need to be powered and it's the best way to power things is light because it's everywhere and it's the only form of energy we can see. Batteries are useful in plenty of applications where you want to power a particular device for a certain amount of time. Also batteries need to be recycled or should be recycled but currently this is not the case. 90% of batteries are ending up in the landfill. So if you have an application where you don't want to have to continuously change a battery you might have something that's out of reach or you want continuous power supply then we have an alternative solution that can power that continuously. Dyson Citi solar cells are the most efficient affordable technology for indoor applications. More efficient than silicon or gallium as a night. We're making systems that are easy to scale up. They're cheap to make continuously. They use a form of principal technology which harvest light under ambient conditions as well as in direct sunlight and because they can be produced on a range of different substrates particularly metal foils or plastics they can be integrated directly into portable electronics or even building materials. Dyson Citi solar cells are very exciting technologies. This is a beautiful playground for any chemist because on the molecular level we can change and tune every component of this photo all time. The things that we can do here that we can't do elsewhere is have the combination of skills that we need. So from making inorganic materials to characterising them using state-of-the-art techniques working with colleagues to develop new types of dyes to capture light effectively and then really advance spectroscopy so that we can monitor all the processes that happen within the device over all of the time scales that they operate and that gives us real insight so that we can make our materials better and then make our devices better. So if you're interested in joining us in finding new ways and new solutions to apply sunlight empowering new smart technology and solving the challenge of clean and affordable energy then get in touch.
