Green Synthesis of TiO₂ Nanoparticles Using Averrhoa Bilimbi Fruits Extract and DPT-PEG Polymer Electrolyte for Enhance Dye-Sensitized Solar Cell Application

Abstract

Green synthesis of nanoparticles has grown substantial interest as a developing technology to reduce the toxicity of metal oxide commonly associated with conventional physical and chemical synthesis methods. Among these, green synthesis of nanoparticles from plants parts to be a very active method in developing nontoxic, eco-friendly and clean technology. We prepared green synthesized TiO2 using a fruits extract of Averrhoa bilimbi with a cost effective and non-toxic method and reports better PCE of DSSCs application. The green synthesized TiO2 nanoparticles (working electrode) with DPT dopant PEG polymer electrolyte shows better power conversion efficiency in dye-sensitized solar cells. The green TiO2 was characterized with XRD, UV, FTIR, SEM, TEM and EDX techniques analysis the band gap, crystallite size and shape for green synthesized TiO2 nanoparticles. The electrical and mechanical properties of DPT organic doped PEG/KI/I2 polymer electrolyte were characterized with XRD, FTIR, EIS, DSC and TGA and it was analysis that the DPT well miscible with PEG polymer electrolyte and improves the electrical conductivity and enhances the efficiency of DSSC.
