Nanostructured g-C3N4-decorated TiO2 for superior photoanode performance in dye-sensitized solar cells

This article explores the potential of a novel photoanode material, g-C3N4 doped TiO2 in improving the photon-to-current conversion efficiency of standard dye-sensitized solar cells. The hybrid nanocomposite photoanode shows a higher light conversion efficiency compared to traditional sintered anatase TiO2 (T400). A novel solvothermal method is used to synthesize and assess the performance of the g-C3N4 doped TiO2 as a photoanode for electron collection in dye-sensitized solar cells (DSSC). The results indicate an optimal efficiency of 9% for the fabricated DSSC with g–C3N4/TiO2 (g-TO) nanocomposite photoanode, surpassing the efficiency of DSSCs with TiO2 (T400) as a photoanode. The research presented here highlights that g-C3N4/TiO2 exhibits outstanding properties and holds great potential for implementation in photo energy conversion devices for practical applications.
