摘要：

In this paper, hole-free, carbon-based all-inorganic CsPbI3 perovskite solar cells (PSCs) with the structure of F-doped SnO2 (FTO)/ZnO/CsPbI3/C are fabricated at a low temperature for the first time. Excess CsBr is added into CsPbI3 precursor solution to obtain stable black phase CsPbI3 at a low temperature (120 °C). ZnO is prepared by a spin-coating method at 120 °C. And then the C electrode is prepared by a doctor-blade method at 120 °C. The effect of different layers of ZnO on the performance of solar cells is investigated. The champion p...
