A team of UCLA researchers has achieved a breakthrough in polymer solar cell (PSC) technology by doubling the efficiency of the transparent solar cells they unveiled last year. Led by Yang Yang, Director of the Nano Renewable Energy Center of California Nano Systems Institute, the team has been developing solar cells made from PSC – a photoactive plastic that converts infrared light into an electrical current. It’s nearly 70% transparent because it produces energy by absorbing mainly infrared light. The new PSC could be applied as film on windows and cell phone displays without compromising the user’s ability to see through the surface.
