| Cell Reports Physical Science Verified
Summary Halide perovskites are semiconductors that have impacted the photovoltaic field in single and multijunction devices. Among them, metastable FAPbI3-based (FA, formamidinium) and CsPbI3-based perovskites are frontrunner materials for perovskite solar cells. However, they face the same challenge; their photoactive black perovskite phases spontaneously transform into the yellow non-photoactive δ phases at room temperature.

Abstract : In Lubumbashi, the capital of Haut Katanga in the Democratic Republic of the Congo (DR Congo), diesel power plants are a common source of electricity. The need to utilize local renewable energy sources in DR Congo has increased due to the unreliability of the state grid and the rising cost of running diesel generators. Solar photovoltaic (PV) panels and batteries, in particular, have recently recorded significant price drops.
