摘要：
This study investigates the effect of various concentrations of Tungsten Oxide (WO3) nanoparticles on the performance of dye sensitized solar cells. For that WO3 nanoparticles are synthesized by using solvothermal method and annealed at room temperature, 100 and 400 A degrees C. The crystalline and morphology of the synthesized WO3 nanoparticles was characterized by X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). Solar cell with 1 % WO3 nanoparticles (annealed at 100 A degrees C) added TiO2 electrode exhibits an enhanced short-circuit current density of 12.94 mA cm(-2), open-circuit photo voltage of 0.67 V, fill factor of 0.57, and overall power conversion efficiency of 5.03 %.
