Solar cells for windows
A team at UCLA have developed a transparent solar cell that is an advance toward giving windows in homes and other buildings the ability to generate electricity while still allowing people to see outside. Based on the PEDOT:PSS polymer with a silver metal oxide composite electrode, the devices can exhibit a 66% transparency whilst simultaneously giving a 4% power conversion efficiency. The polymer solar cells are lightweight, flexible and can be produced in high volumes and at low costs.
