Dot Sensitized Solar Cells

In this work we have used CuS/PbS nanocomposite as a counter electrode for CdS/CdSe quantum dotsensitized solar cells (QDSCs) by successive ionic layer adsorption and reaction (SILAR) method. The efficiency of cells was 3.58% with CuS/PbS nanocomposite counter electrode which is considerably higher than that CuS and PbS CEs in QDSCs. Our result indicates that the cells’ efficiency has increased more than 2 and 3 times in comparison with CuS CEs (0.99%) and PbS CEs (1.47%) respectively.
