Flexible dye-sensitised solar cells (FDSSCs) which have different quantities of arrayed titanium dioxide (TiO2) working electrode for parallel modules are introduced. FDSSCs are usually fabricated as a module type instead of single cell to enhance conversion efficiency and characteristic parameters. The general FDSSCs modules are designed as parallel strip-shaped and as parallel interconnection types, and there are some advantages such as easy fabrication, low cost and simple structure. In this reported study, the active areas of FDSSCs are the same (0.48 cm2), and they have different quantities of TiO2 thin films. The single strip-shaped TiO2 working electrode has a larger internal resistance than more quantities of TiO2 thin films. Therefore, and they have fabricating the different quantities of arrayed flexible TiO2 working electrodes is the better method to solve the problem, higher internal resistance than single TiO2 thin film. As a result, the FDSSC, which has the triple strip-shaped TiO2 working electrode, has a higher conversion efficiency (0.25%) than other different quantities of TiO2 thin films.
