Cu-Doped-CdS/In-Doped-CdS Cosensitized Quantum Dot Solar Cells

Cu-doped-CdS and In-doped-CdS cosensitized (Cu-doped-CdS/In-doped-CdS) quantum dot solar cells (QDSCs) are introduced here. Different cosensitized sequences, doping ratios, and the thickness (SILAR cycles) of Cu-doped-CdS and In-doped-CdS are discussed. Compared with undoped CdS QDSCs, the short cir...

Zusammenfassung:Cu-doped-CdS and In-doped-CdS cosensitized (Cu-doped-CdS/In-doped-CdS) quantum dot solar cells (QDSCs) are introduced here. Different cosensitized sequences, doping ratios, and the thickness (SILAR cycles) of Cu-doped-CdS and In-doped-CdS are discussed. Compared with undoped CdS QDSCs, the short circuit current density, UV-Vis absorption spectra, IPCE (monochromatic incident photon-to-electron conversion), open circuit voltage, and so on are all improved. The photoelectric conversion efficiency has obviously improved from 0.71% to 1.28%.
