UCLA creates transparent solar cell, dreams of current generating windows


Transparent photovoltaics have yet to grace the face of your smartphone, but don't give up hope -- UCLA researchers are working on a new see-through solar cell that's showing potential. Using a new type of polymer solar cell, the team has been able to build a device that converts infrared light into electrical current. Current prototypes boast 4 percent energy conversion efficiency at 66 percent transparency -- not crystal clear, but certainly clean enough to peer through. According to a study in ACS Nano, the technology could be used in "building-integrated photovoltaics or integrated photovoltaic chargers for portable electronics." Translation? It could one day be used to build solar windows or better sun collecting smartphones. Don't get too excited though, the technology still has a ways to go before any of these dreams come to fruition. Still, feel free to head past the break for the team's official press release, or skip to the source to take in the full academic study.
