Flexible dye-sensitized solar cells (FDSSCs) have many advantages such as light weight, good flexibility and impact resistance, which have attracted extensive attention of researchers. As an important part of the battery, the photoanode is the region of electron excitation and collection, and its performance determines the conversion efficiency of the battery. Firstly, the structure and working mechanism of FDSSC are briefly introduced, then the research progress of the cell photoanode is reviewed, and the preparations of the plastic and metal base photoanodes are emphatically discussed. Finally, the future development opportunities and challenges of FDSSC are summarized, so as to provide reference and help for the preparation of the battery.
