Sensitized Solar Cells

CdS/CdSe quantum dots co-sensitized solar cells (QDSCs) were 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. In this work, we designed anisotropic nanostructure ZnO photoelectrodes, such as nanorods/nanosheets and nanorods array, for CdS/CdSe quantum dots co-sensitized solar cells. Our study revealed that the performance of QDSCs could be improved by modifying surface of ZnO to increase the loading of quantum dots and reduce the charge recombination.

Cdse Quantum Dot

An inverted bulk-heterojunction hybrid solar cell with the structure ITO/ZnO/P3HT:PbS/Au was prepared. The device performance was enhanced by inserting an interface buffer layer of CdSe quantum dots between the ZnO and the P3HT:PbS BHJ active layer.
