Abstract
In this work, novel surface defected lead-free double perovskite oxide (Sr2FeTeO6) has been introduced in dye sensitized solar cells (DSSCs) for the first time. The Sr2FeTeO6 material prepared by solid state method treated at 1200 °C. The DSSC was performed with varying weight percentage (0.01 wt%, 0.03 wt%, 0.05 wt%) of Sr2FeTeO6 additives incorporated with titanium di-oxide (TiO2) photoanode for light harvesting under AM 1.5 solar irradiation. The inorganic double perovskite oxide material as promising additive would be in the future developing 3rd generation solar cell technologies.
