Abstract

A Cu₂S–CuInS₂–ZnSe quantum dot (QD)-sensitized solar cell with cascaded energy gap structures has been fabricated. Under simulated illumination (AM 1.5, 100 mW cm⁻²), the best device is obtained with a Cu₂S–CuInS₂–ZnSe QD-sensitized solar cell, yielding a power conversion efficiency of 2.52%.
