文摘
- •
The degradation process of perovskite solar cells (PSCs) was disclosed using in-situ experiments.
- •
The formation of large amount of bubbles at the interface resulted in the sharp degradation.
- •
The degradation driven by intrinsic decomposition of perovskite itself under atmosphere was not obvious.
- •
The annealing-free TiO2 NPs as an interface modification layer dramatically improved the stability of PSCs.
