Abstract
In this study, the variation of characteristics of P-25 photocatalyst with calcination temperature(Pure: non-thermally treated, 450, 650, $850^{\circ}C$) was studied. The photocatalysts were used as working materials for dye-sensitized solar cells: DSSCs) later on and their photovoltaic characterization was carried out. The photocatalytic degradation of methylene blue using the P-25 photocatalyst with different calcination temperature was almost same expect for $850^{\circ}C$. The solar energy conversion efficiency ($\eta$) of DSSCs prepared by the nanoparticles (photocatalyst) reached 6.9% (for pure), 6.5%(for 450), 5.8%(for 650) and 5.6%(850).
