Abstract

Chalcopyrite flower-like CuInS2 were successfully synthesized by a one-step solvothermal method and has been applied as a counter electrode for efficient dye-sensitized solar cells. The as-synthesized flower-like CuInS2 were composed of nanoplates. The prepared CuInS2 powders occupy energy band gaps of 1.38 eV, which is considerably approaching to ideal band gap for optimum solar energy conversion via the photovoltaic effect. The dye-sensitized solar cells with flower-like CuInS2 as a counter electrode can yield 4.5 % photoelectric conversion efficiency.
