Comparison and Analysis of the third generation of the solar cells

Abstract

Since the current energy crisis, the efficiency of using solar cell energy has become increasingly important. In order to get a high efficiency, new kinds of solar cells would be needed, which called the third generation of solar cells. This paper review three kinds of solar cells, including the perovskite solar cells, the quantum dots solar cells and the organic solar cells. Firstly, the structure of perovskite solar cells is composed of a FTO conducting glass, a TiO2 blocking layer, a TiO2 mesoporous layer, a perovskite layer, a HTM (Hole Transport Material) layer, and mental electrode. Then, I sum up the manufacture and the development of the perovskite solar cells. Secondly, this paper analysis the structure, manufacture, and development of quantum dots solar cells. The structure of quantum dots solar cells includes the transparent conducting oxide, wide bandgap oxide semiconductor film, quantum dot sensitizer, electrolyte, and counter electrode. The third one is the organic solar cells. The structure of the organic solar cells includes layer, cathode, anode, and transparent substrate. Finally, this paper reviews the merits and defects of each solar cells.
