Effect of Mn Doping on Properties of CdS Quantum Dot-Sensitized Solar Cells
Quantum dot-sensitized solar cells (QDSSCs) have received extensive attention in recent years due to their higher theoretical conversion efficiency and lower production costs. However, the photoelectric conversion efficiency of QDSSCs is still lower than the DSSCs because of the severe recombination...

| description | Quantum dot-sensitized solar cells (QDSSCs) have received extensive attention in recent years due to their higher theoretical conversion efficiency and lower production costs. However, the photoelectric conversion efficiency of QDSSCs is still lower than the DSSCs because of the severe recombination of electrons of quantum dots conduction band. In order to improve the photoelectric conversion efficiency of QDSSCs, impurity element Mn2+ is doped into the precursor solution of cadmium sulfide (CdS). By optimizing the experimental parameters, the photoelectric conversion efficiency of QDSSCs can be greatly improved. For the deposition of a fixed number of six times, the photoelectric conversion efficiency shows the maximum value (1.51%) at the doped ratio of 1 : 10. |
