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.

利用 Sr2FeTeO6 添加剂提高 DSSC 中 TiO2 的采光能力

这项研究首次在染料敏化太阳能电池（DSSC）中引入了新型表面缺陷无铅双包晶氧化物（Sr2FeTeO6）。Sr2FeTeO6 材料采用固态方法制备，并在 1200 °C 下进行处理。在 AM 1.5 太阳辐照条件下，采用不同重量百分比（0.01 wt%、0.03 wt%、0.05 wt%）的 Sr2FeTeO6 添加剂与二氧化钛（TiO2）光阳极结合进行光收集，从而实现了 DSSC。无机双包晶氧化物材料作为一种有前途的添加剂，将在未来开发第三代太阳能电池技术中大有作为。
