Bismuth-interlayer-based Stable Electrode for Efficient and Stable Halide Perovskite Solar Cell

Highly efficient and low-cost halide perovskite solar cells(PSCs)have attracted great attention over the last few years as one of the most promising photovoltaic(PV)technologies.Yet,to gauge the technical feasibility for commercialization of PV technologies,the long-term stability of PSCs is still a challenge that must be addressed[1].
