Efficient carbon counter electrodes for BaSnO3-based dye-sensitized solar cells

Abstract Natural source derived carbon materials make them ideally suited alternative to costly Pt counter electrode for their good catalytic activity, resistance to iodine corrosion, and high stability of the device. Apart from the extensively acclaimed photoanode TiO2, BaSnO3 (BSO) has been projected as an efficient alternative to it. In this study, remarkable efforts have been endeavoured to establish BSO-carbon-based dye-sensitized solar cell (DSSC) device. Investigation on the adequate performance of natural source derived carbon-based counter electrodes for BSO-based DSSCs, explored as a significant alternative to costly Pt and TiO2, respectively, which could elucidate better photo-stability and more extended device performance compared to TiO2-Pt-based DSSCs.
