Progress of Quantum Dot Research Sensitized Solar Cells

The structure and operation principle of quantum dot sensitized solar cells,and the feature of quantum dot sensitizer are reviewed.Quantum dot sensitizer are classified according to their composition,the correspon-ding research progress are introduced.The structure of quantum dot sensitizer and large band gap materials affect the performance of solar cells markedly.If the size of quantum dot sensitizer are gradient increase,a wide scope of sunlight can be absorbed.Besides,quantum dot sensitizer attaches on one-dimensional nanowires or nanotubes array which stand on conducting substrate,then the photo generated electron will be transferred to electrode directly,the efficiency of solar cells can be improved obviously.At last,the present problems and research direction in the future are also described.
