Computational Investigation of ZnTiO3 Perovskite Based Photo-anode for Dye Sensitized Solar Cell Application.

Abstract

Dye-sensitised solar cells continue to be a promising photovoltaic technology for indoor and outdoor applications, with increased interest in power window applications integrated into buildings. This results from properties not seen in other, more established solar technologies, such as the range of available colours, partial transparency and good performance under low light intensities or in partial shade. TiO2 and ZnO materials being developed and reported in the literature are the best candidates as photo-electrode in DSSC, since both of TiO2 and ZnO metal oxides have their own advantages, combining both of them may yield a new hybrid system with higher performance of DSSC. in this work the perovskite ZnTiO3 is investigated to combine the benefits of both TiO2 and ZnO materials in term of chemical stability, excellent charge transport and high electron mobility, high surface area and suitable band gap and CBE, eventually a best photoanode for dye sensitised solar cell.
