Highly efficient core–shell CuInS2–Mn doped CdS quantum dot sensitized solar cells

A simple aqueous solution route has been used to prepare mercaptoacetic acid attached CuInS2 quantum dots. Based on this material, core–shell CuInS2–Mn doped CdS quantum dot sensitized solar cells are assembled and a power conversion efficiency of 5.38% is obtained under AM1.5 (100 mW cm−2) illumination.
