Outline of Final Research Achievements

Fabrication and characterization of perovskite solar cells using soluble metal phthalocyanine complex as hole-transporting layer were performed. Additive effects of metal phthalocyanines into spiro-OMeTAD as hole-transporting layers on the photovoltaic and optical properties, microstructure was investigated. Control of molecular structure with adding a small amount of metal phthalocyanine as hole-transporting layer influenced the perovskite crystal growth, band structure, the transporting behavior, photovoltaic properties, and conversion efficiency. The photovoltaic and optical properties with long-term stability were improved by optimization of the doping condition. The photovoltaic mechanism was revealed on the basis of the electronic structure using first-principles calculation.
