Furthermore, optoelectronic and photoelectrochemical devices, in particular photovoltaic devices, organic-inorganic perovskite films, layered photovoltaic devices, p-n heterojunctions, dye-sensitized solar cells, organic solar cells and solid state solar cells, comprising such hole transport materials or hole transport compounds are described. It is notable that a perovskite solar cell module manufactured using the disclosed HTM compound exhibits a recording efficiency of more than 19.0% and an effective area of 30.24 cm2.patentJP7497941JP2023072638US2023157158EP4181225CN11613344481346354
