Promising strategies for durable perovskite solar cells
Tue, Oct 27, 2020 - 3:00 pmPerovskite materials are becoming increasingly popular as the active layer in solar cells. Internal forces in these materials cause distortions in their crystal structures, reducing symmetry and contributing to their intrinsic instability. They are also subject to environmental degradation.
