Long-duration stability of perovskite solar cells

US scientists have analyzed the impact of "seasoning" a formamidinium lead iodide solution with two-dimensional (2D) perovskites. They have found that the template improved the efficiency and durability of their solar cells. Scientists from Rice University in Houston, Texas, have improved the stability of pervoskite solar cells by distributing 2D perovskites. The scientists synthesized formamidinium lead iodide (FAPbI3) into ultrastable, high-quality photovoltaic films for high-efficiency perovskite solar cells. They hypothesized that using more stable 2D perovskites as a template could impart ...
