Understanding the love-hate relationship of halide perovskites with the sun

Solar cells made of perovskite are at the center of much recent solar research. The material is cheap, easy to produce, and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite cells have a love-hate relationship with the sun. The light that they need to generate electricity, also impairs the quality of the cells, severely limiting their efficiency and stability over time. Research by scientists at the Eindhoven University of Technology and universities in China and the U.S. now sheds new light on the causes of this degradation and paves the way for designing new perovskite compositions for the ultimate stable solar cells.
