摘要: Abstract Tin(IV) oxide nanoparticles (SnO2 NPs) doped on the surface of graphene (GO) sheets for application in Dye-Sensitized Solar Cells (DSSCs). The effective incorporation SnO2 GO were confirmed by powder X-ray diffraction (PXRD), Fourier transform infra-red spectroscopy (FT-IR), thermogravimetric analysis (TGA), electrochemical impedance (EIS), and Raman spectroscopy. morphology GO/SnO2 hybrid nanocomposite was field emission scanning electron microscopy (FE-SEM) analysis. This current study involvement with effect different photo-anodes such as GO, SnO2, power conversion efficiency (PCE) triiodide electrolyte based DSSCs. Remarkably, photo-anode DSSC observed PCE 8.3% it is about 12% higher than that un-doped TiO2 photo-anode. equivalent short-circuit photocurrent density (Jsc) 16.67 mA cm−2, open circuit voltage (Voc) 0.77 V, fill factor (FF) 0.65 respectively. achieved results propose an appropriate photo-anodic material DSSCs applications.
