Abstract
Traditional dye-sensitized solar cells (DSSC) use FTO/ITO containing expensive rare elements as electrodes, which are difficult to meet the requirements of flexibility. A new type of flexible DSSC structure with all-metal electrodes without rare elements is proposed in this paper. Firstly, a light-receiving layer was prepared outside the metal photoanode with small holes to realize the continuous oxidation-reduction reaction in the electrolyte; Secondly, the processing technology of the porous titanium dioxide (TiO2) film was analyzed. By testing the J–V characteristics, it was found that the performance is better when the heating rate is slow. Finally, the effects of different electrode material combinations were compared through experiments. Our results imply that in the case of all stainless-steel electrodes, the open-circuit voltage can reach 0.73 V, and in the case of a titanium photoanode, the photoelectric conversion efficiency can reach 3.86%.

Electrode cost is a problem in the research of photoanodes and counter electrodes (CE) [7,8]
Summary
Metal and metal compound electrodes have been extensively studied in DSSC. Due to their opacity, most of them are limited to the use of a single metal electrode [1,2,3,4,5,6]. The photoanode in DSSC should have the functions to adsorb dyes [12] and transmit and collect photogenerated electrons. The traditional sandwich DSSC uses expensive FTO electrodes, which reduce the cost performance, and at the same time, due to its rigidity, the battery loses its flexibility.
