The Influence of Dopant Concentration on Optical-Electrical Features of Quantum Dot-Sensitized Solar Cell.

In this study, TiO/CdS/CdCuSe, TiO/CdS/CdMnSe, and TiO/CdS/CdAgSe thin films were synthesized by chemical bath deposition for the fabrication of photoanode in quantum-dot-sensitized solar cells. As a result, the structural properties of the thin films have been studied by X-ray diffraction, which confirmed the zinc Blende structure in the samples. The optical films were researched by their experimental absorption spectra with different doping concentrations.
