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。
In order to stabilize the perovskite solar cells after annealing at high temperature, zinc oxide / graphene oxide nanoparticles were prepared electrochemically and applied to the perovskite solar cells as the electron transport layer. The ZnO films deposited on zinc oxide and zinc oxide / graphene oxide were characterized by in-situ grazing incidence X-ray diffraction (XRD), X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis absorption spectroscopy Nanomaterials above the methylamine lead iodine structure, morphology and battery performance changes were analyzed and tested. The results show that zinc oxide / graphene has a protective effect on lead and lead methylamine, and the lead methylamine film deposited on the zinc oxide / graphene oxide has higher stability and more stable battery performance, thus providing a large area of application Certain guidance.
