The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has been rapidly improved, and the world's highest PCE has exceeded 26%. Scientists expect PCE to continue to improve in the future. Moreover, when PSCs are prepared in air, factors such as humidity and temperature can significantly affect the performance of the resulting perovskite film. In addition, the current study found that the effect of humidity on the quality of perovskite films is more beneficial than harmful. In this paper, the effect of water on the preparation of perovskite films is reviewed, and the optimization method for the preparation of perovskite films at normal temperature is discussed. By reducing the effect of humidity on perovskite films, high performance perovskite films are prepared, thereby achieving improved performance of PSCs and creating opportunities for commercialization of high-quality, stable and large-scale PSCs.

摘要

The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has been rapidly improved, and the world's highest PCE has exceeded 26%. Scientists expect PCE to continue to improve in the future. Moreover, when PSCs are prepared in air, factors such as humidity and temperature can significantly affect the performance of the resulting perovskite film. In addition, the current study found that the effect of humidity on the quality of perovskite films is more beneficial than harmful. In this paper, the effect of water on the preparation of perovskite films is reviewed, and the optimization method for the preparation of perovskite films at normal temperature is discussed. By reducing the effect of humidity on perovskite films, high performance perovskite films are prepared, thereby achieving improved performance of PSCs and creating opportunities for commercialization of high-quality, stable and large-scale PSCs.
