Effect of the photoanode fabrication condition, electrolyte type and illumination type on dye-sensitized solar cells performance

The combination of the photoanode fabrication condition, electrolyte type and light source effect on dye-sensitized solar cell (DSSC) performance were investigated. Three different photoanodes (C1, C2 and C3) were used with different fabrication conditions with two different redox concentration electrolytes (30 and 50 mM) for each photoanode. For these six different combinations, DSSC performances were obtained for 12 different situations using two different light sources, AM 1.5 simulated and ultraviolet (UV-365 nm) illumination. It was obtained that the HI30 electrolyte has higher efficiency for UV illumination and the AN50 electrolyte has higher efficiency for AM1.5 simulated illumination. It was also obtained that the C2 cell with double layer immersed in dye solution has higher efficiency for both two illumination types and two electrolytes.
