Strong cells - performance upgrade with mini modules

A new molecular hole-transporter can improve the performance of inverted perovskite solar cells and mini modules to world record values, as reported in "Science" by Prof. Yongzhen Wu (East China University of Science and Technology) and his international team, including physicists from the University of Potsdam.

Improving the lifetime energy yield from solar cells is an important factor to become independent from fossil energy sources. Inverted perovskite solar cells are particularly promising because of their very simple fabrication at low costs and their stability allowing them to pass several stability tests of the International Electrotechnical Commission (IEC). ...
