Description

Metal halide perovskites (MHPs) have attracted great attention in recent years due to their enormous potential for application in optoelectronic devices. However, the defects at surface/interfaces and grain boundaries of perovskite films, which impede the further enhancement of power conversion efficiency (PCE) and long-term stability of halide perovskite solar cells (PSCs), still need to be fully understood. Here, we studied the impact of different growth conditions on the interface and grain boundaries of CH$_3$NH$_3$PbI$_3$ perovskite films by low-energy $\mu$SR. Our measurements show that low-energy $\mu$SR can become a powerful technique for studying the defect engineering of PSCs.
