Substituting expensive traditional hole transporting material (HTM) with cheaper inorganics is a key factor for perovskite photovoltaics commercialization. Cu2O is a promising p-type semiconductor exhibiting good band-alignment with perovskite. However, due to solvent and temperature incompatibility...
