Spontaneous bifacial capping of perovskite film for efficient and mechanically stable flexible solar cell

Junjun Jin, Zhenkun Zhu, Yidong Ming, Yuan Zhou et autres

Flexible perovskite solar cells (F-PSCs) are appealing for their flexibility and high power-to-weight ratios. However, the fragile grain boundaries (GBs) in perovskite films can lead to stress and strain cracks under bending conditions, limiting the performance and stability of F-PSCs. Herein, we …
