Solid-state dye-sensitized photovoltaic device with newly designed small organic molecule as hole-conductor

A newly small organic molecule, (R)-2,2′-dimethoxyl-3,3′-di(phenyl-4-yl-diphenyl-amine)-[1,1′]-binaphthyl, was introduced into solid-state electrolyte to assemble dye-sensitized solar cell, which showed an attractive conversion efficiency of 0.55%. The positive effects of additives in electrolytes on the photoelectrical performance were discussed in detail.
