Thermal Stable Perovskite Solar Cells Improved by ZnO/Graphene Oxide as Electron Transfer Layers

Keywords： GIXRD , ZnO/GO , perovskite , ETL (electron transfer layers)

为了使钙钛矿太阳能电池在高温退火后能够保持稳定,本研究通过电化学方法制备出氧化锌/氧化石墨烯纳米粒子,并将其运用到钙钛矿太阳能电池中作为电子传输层使用.通过原位掠入射X射线衍射(GIXRD)、X射线衍射(XRD)、扫描电子显微镜(SEM)和紫外-可见吸收光谱(UV-Vis)等方法对沉积在氧化锌和氧化锌/氧化石墨烯纳米材料上面的甲胺铅碘的结构、形貌以及电池性能变化进行分析测试.结果表明:氧化锌/氧化石墨烯对于甲胺铅碘有保护作用,沉积在氧化锌/氧化石墨烯上面的甲胺铅碘薄膜稳定性更高,电池性能更加稳定,为将来大面积应用提供了一定的指导.
