Spray-on solar
Researchers at the University of Texas are developing solar photovoltaics 10,000 times thinner than human hair that can be spray-painted onto surfaces. The ambition of the project is to develop a solution of sunlight-absorbing nanoparticles that can be sprayed onto a surface to create a solar panel–a process similar to newspaper printing. The technology they’re working with uses copper indium gallium selenide instead of silicon and could be cheaper than fabricating conventional solar panels.
