Abstract
In this study, we report a breakthrough in perovskite SrTiO3 by enriching the open circuit voltage and power conversion efficiency through Cr doping. Our findings demonstrate a remarkable improvement of 219% in the short-circuit current density (Jsc) for SrTi0.95Cr0.05O3 photoelectrodes compared to pristine SrTiO3. Additionally, we achieved a power conversion efficiency of 5.62% in nanoparticles of SrTi0.95Cr0.05O3 with TiO2 scattering layer photoanodes. The impressive results were achieved due to the higher dielectric constant and high conductivity of the material, which paves the way for replacing traditional TiO2 as an electron transporter in future DSSC technology.
