摘要：

Conventional perovskites solar cells have been afflicted with serious hysteresis effect, resulting in difficult to accurate the real power conversion efficiency of devices. Here, an additive of KSCN was applied to enhance the crystallization of perovskite crystals, increased the perovskite grain size, reduced the density of defects, led to a high-quality thin film. Correspondingly, devices with a power conversion efficiency of 19.23% and fill factor of 75.08% under AM 1.5G 100 mW cm(-2) irradiation were achieved. In comparison with typical devices, these solar cells showed improved photovoltaic performance, stability, reproducibility, carrier mobility and lower hysteresis effect, which was attributed to the high-quality thin film. Our work demonstrated a facile and effective approach for fabricating solar cells with no-hysteresis and high-performance towards commercialization.
