| 摘 要： | 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。

| Abstract: | ZnO/graphene oxide (GO) nano-particles (NPs) layer was prepared using a facile solution process and employed as an electron conductor to improve the thermal stability of perovskite solar cells. Structural changes during the degradation process in high temperature environment were characterized via in situ grazing incidence X-ray diffraction. The optical properties and surface morphologies of the films were characterized. It was observed that smooth and compact structure of ZnO/GO layer works as a protection layer to prevent decomposition of perovskite film which is converted into PbI2 during the annealing process reaction. The perovskite film grown on ZnO/GO layer exhibited enhanced crystallization, high surface coverage ratio as well as preferred in-plane orientation of the (110) plane. |
