Very cool idea: a “highly transparent” solar cell that can be applied to windows, generating electricity while still enabling people to use the window for its basic purpose: looking out.
The UCLA 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 made the device from a photoactive plastic that converts infrared light into an electrical current. ... Yang added that there has been intense world-wide interest in so-called polymer solar cells. "Our new PSCs are made from plastic-like materials and are lightweight and flexible," he said. "More importantly, they can be produced in high volume at low cost."
The research was published in the current issue of the journal ACS Nano.
