Metal-halide perovskites show remarkably clean semiconductor behaviour, as evidenced by their excellent solar cell performance, in spite of the presence of many structural and chemical defects. Here, we show how this clean semiconductor performance sets in during the earliest phase of conversion from the met
Furthermore, the stability of the absorbing perovskite materials can be enhanced by carefully selecting a hydrophobic electron and hole transporting layer (ETL/ HTL) of a perovskite PV cell [34].
