CsPbCl(3)‐Driven Low‐Trap‐Density Perovskite Grain Growth for >20% Solar Cell Efficiency

Charge recombination in grain boundaries is a significant loss mechanism for perovskite (PVK) solar cells. Here, a new strategy is demonstrated to effectively passivate trap states at the grain boundaries. By introducing a thin layer of CsPbCl(3) coating before the PVK deposition, a passivating laye...
