Fabrications of TiO_2 Photoanodes for Flexible Dye-sensitized Solar Cells

Flexible dye-sensitized solar cell(FDSSC) is a type of dye-sensitized solar cell(DSSC) based on flexible substrates,such as plastics and metals,etc. The advantages of FDSSC over rigid DSSC involve bendability,lower cost,ease of large-scale production and wider application,which make it attract much attention. The fabrication methods for FDSSC photoanodes are generally categorized to low-temperature fabrications and high-temperature fabrications,including chemical additive method,mechanical compression,electrophoretic deposition,lift-off method,and some new technologies. This paper reviewed the above fabrication methods and the performance of the cells was discussed by taking into account the mechanisms for electron transfer and recombination. Finally,the future development of FDSSC was prospected.
