High-performance perovskite solar cells (PSCs) based on organometal halide perovskite have emerged in the past five years as excellent devices for harvesting solar energy. Some remaining challenges should be resolved to continue the momentum in their development. The photocurrent density–voltage (J−V) responses of the PSCs demonstrate anomalous dependence on the voltage scan direction/rate/range, voltage conditioning history, and device configuration. The hysteretic J–V behavior presents a challenge for determining the accurate power conversion efficiency of the PSCs. Here, we review the recent progress on the investigation of the origin(s) of J–V hysteresis behavior in PSCs. We discuss the impact of slow transient capacitive current, trapping and detrapping process, ion migrations, and ferroelectric polarization on the hysteresis behavior. The remaining issues and future research required toward the understanding of J–V hysteresis in PSCs will also be discussed.

钙钛矿太阳能电池的J – V磁滞现象的起源

在过去的五年中，基于有机金属卤化物钙钛矿的高性能钙钛矿太阳能电池（PSC）成为收集太阳能的出色设备。应该解决一些尚存的挑战，以继续其发展势头。PSC的光电流密度-电压（J - V）响应显示出异常依赖于电压扫描方向/速率/范围，电压调节历史和设备配置。滞后的J – V行为对确定PSC的准确功率转换效率提出了挑战。在这里，我们回顾了J – V起源研究的最新进展PSC中的磁滞行为。我们讨论了缓慢的瞬态电容电流，俘获和去俘获过程，离子迁移和铁电极化对磁滞行为的影响。还将讨论理解PSC中的J - V磁滞所需要解决的其余问题和未来的研究。
