英文摘要：

TiO2 photoanodes with different structures played a vital role in enhancing photovoltaic performance of the quantum dot solar ceils （QDSCs） and great photovoltaic performance can be promoted by engineering multiple structures of TiO2 photoanode efficiently. Multiple TiO2 photoanodes with various structures, such as 0 dimensional （0-D） nanostructures, 1-D nanostructures, 2-D nanostructures and composite nanostructures, are reviewed emphati- cally. Its applications and development trends as well as the basic principle and structure of QDSCs are presented. Simultaneously, the advantages and disadvantages of different structure of TiO2 photoanode are discussed and effective approaches to improve the conversion efficiency of QDSCs are pointed out as well.
