Researchers from UCLA have developed a new transparent solar cell that is a significant step towards giving the windows in homes and other buildings the ability to generate electricity while still being transparent.
The research team “describes a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent to the human eye.” They created the device from a photoactive plastic that generates an electrical current from infrared light.
“These results open the potential for visibly transparent polymer solar cells as add-on components of portable electronics, smart windows and building-integrated photovoltaics and in other applications,” said study leader Yang Yang, a UCLA professor of materials science and engineering, who also is director of the Nano Renewable Energy Center at California NanoSystems Institute (CNSI)
