Semi-transparent organic solar cell for window applications

Developed by U.S. scientists, the 10%-efficient device is intended for applications in solar windows and promises efficiencies close to 15%. According to its creators, the cell retained 80% of its efficiency after 1,900 hours at 55 degrees Celsius.A group of researchers at the University of Michigan has developed an organic solar cell with a transparency of 40% and an efficiency of around 10%. Conceived for applications in PV windows, the non-fullerene cell was fabricated with the polymer PCE-10 as a donor, and a near-infrared (NIR) absorbing, non-fullerene acceptor (NFA) known as BT-CIC, in an ...
