Abstract

Organic-inorganic hybrid perovskite solar cell (PSC) has received widespread attention due to its high efficiency, low cost, and easy fabrication process. However, the commercialization of PSC is still hindered due to their unstable properties. Current density-voltage (J–V) hysteresis is one of the instabilities that causes overestimate or underestimate of the real conversion efficiency of PSC, making it difficult to assess the true photovoltaic parameters. This review discusses the internal and external factors that causes the J–V hysteresis phenomenon and presents various strategies to alleviate the J–V hysteresis in PSC. This article also provides insights into the perspectives and critical challenges that are needed to address the hysteresis of PSC for further improvement of device performance.
