Promising strategies for durable perovskite solar cells

Perovskite materials are increasingly popular as the active layer in solar cells, but internal forces in these materials cause distortions in their crystal structures, reducing symmetry and contributing to their intrinsic instability. Researchers examined the mechanisms at play, as well as several degradation factors that influence the performance of perovskite photovoltaics. They clarified the factors influencing the degradation and they summarized some feasible approaches for durable perovskite photovoltaics.
