| 英文摘要 | Understanding the correlation between the lifetime, mobility and diffusion length of photoinduced charge carriers in organolead halide perovskite is essential to successful perovskite-based solar cells. In this paper, through mapping the local photoluminescence (PL) dynamics using laser/PL-scanned confocal imaging microscopy and simulating the carrier diffusion process in an individual CH3NH3PbI3 single-crystalline particle, we report that the rapid diffusion of charge carriers can produce a fast local PL kinetics when the perovskite is partially excited. This result indicates that using PL kinetics to estimate the carrier lifetime in perovskite single crystals needs to exclude the effect of carrier diffusion. |
