Researchers at Michigan State University just developed a new kind of solar cell that’s so crystal clear, even Harry Potter would be impressed. Called the “transparent luminescent solar concentrator,” it uses small organic molecules that absorb invisible wavelengths of sunlight and channel them to strips of photovoltaic cells. Its developers think they could use it to create power-producing windows and self-charging smart phones.
Scientists have created partially transparent solar cells in the past, but the existence of crystal clear cells opens up some very exciting new possibilities. It can be used on tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader.
