CdS/CdSe Co-Sensitized Solar Cell Prepared by Jointly Using Successive Ion Layer Absorption and Reaction Method and Chemical Bath Deposition Process

Abstract

CdS/CdSe quantum dots co-sensitized TiO2 solar cell was prepared by combining the successive ion layer absorption and reaction (SILAR) method and chemical bath deposition (CBD) method for the fabrication of CdS and CdSe quantum dots, respectively. The effect of CdSe deposition time on the solar cell performance was investigated. It was found that the optimized deposition time for CdSe was 3 h, yielding solar cell power conversion efficiency of 3.3%. The methods introduced in this paper are a simple route for the fabrication of quantum dot-sensitized solar cells with achieving descent power conversion efficiency.
