Perovskite solar cells (PSCs) exhibit high energy conversion efficiency of over 25 %, comparable to silicon solar cells. Furthermore, PSCs are expected to expand their applications for installation in the future because of their excellent adavantages such as flexibility, lightweight, and compatibility with a cost-effective. On the other hand, the degradation of PSCs is still serious and needs to be suppressed by elucidating the degradation mechanism for commercialization in the future. Therefore, in this work, we studied the degradation mechanism of perovskite solar cells at high temperature, and aimed to improve the storage stability of perovskite solar cells.
