Metal-Doped Copper Indium Disulfide Heterostructure: Environment-Friendly Hole-Transporting Material toward Photovoltaic Application in Organic-Inorganic Perovskite Solar Cell

摘要： In this plan, we use Praseodymium metal-doped copper indium disulfide (Pr-doped CIS) heterostructure as hole-transporting materials (HTMs) in the FTO/TiO2/Perovskite absorber/HTM/Au device. And photovoltaic performance of these Pr-doped CIS heterostructure was investigated in the fabrication of the organic-inorganic perovskite solar cells (organic-inorganic PSCs).
