Research Progress of Photoanodes for Quantum Dot Sensitized Solar Cells

This paper presents the development status and tendency of quantum dot sensitized solar cells.Photoanode research progress and its related technologies are analyzed in detail from the three ways of semiconductor thin films,quantum dot co-sensitization and quantum dot doping,deriving from the approach that the conversion efficiency can be improved by photoanode modification for quantum dot sensitized solar cells.According to the key factors which restrict the cell efficiency,the promising future development of quantum dot sensitized solar cells is proposed,for example,optimizing further the compositions and structures of semiconductor thin films for the photoanodes,exploring new quantum dots with broadband absorption and developing high efficient techniques of interface modification.
