RETRACTED ARTICLE: Performance enhancement of dye-sensitized solar cells by facile hydrothermal-induced BaSnO3/RGO as photoanode material

As a two-dimensional nanostructure, reduced graphene oxide (RGO) has high specific surface area and excellent conductivity. In this report, we obtain the BaSnO 3 /RGO via facile hydrothermal method and apply it as a photoanode material in dye-sensitized solar cells. A facile hydrothermal method is used to describe the synthesis of RGO hybridization of BaSnO 3 perovskite-type oxide nanopowder and its use as a photoanode replacement in dye-sensitized solar cells. Strutural, morphological, elemental composition and optical properties of the prepared samples were analyzed by X-ray diffraction, Raman, scanning electron microscope, energy dispersive spectra, transmission electron microscope, UV-Vis spectra, photoluminescence and X-ray photoelectron spectra analysis. RGO in the BaSnO 3 photoanode can inhibit charge recombination and thus improve the power conversion efficiency (PCE) of the DSSC. Moreover, the layered structure RGO increases the dye absorption in the BaSnO 3 photoanode and the light harvesting efficiency. As a result, JSC and PCE based on BaSnO 3 /RGO photoanode have considerably increased from 8.45 to 19.51 mA cm −2 , 3.41% to 9.88%. Based on the findings, BaSnO 3 /RGO photoanodes under easily reproducible scientific/rational approach will facilitate an astonishing possibility to enhancing the PCE which confidently reinforce the probability of implementation in practical life and is indispensable for balancing the future non-renewable energy dearth.
