Description
技术领域 technical field

背景技术 Background technique
染料敏化太阳能电池具有价格低廉、环境友好、制作简单、转换效率高等优点，成为第三代太阳能电池的代表。在染料敏化太阳能电池的光阳极材料中，ZnO因为具有高的电子迁移率，容易调控的形貌，合适的能带结构等诸多特点，得到了广泛的研究。为了能够吸附足够多的染料，光阳极材料通常采用纳米ZnO，从而使得电极材料具有一定的透光度，降低了对入射光的利用和电池的整体性能。为了改善电极材料的光收集效率，可在其表面制备一层光散射层，但是以呈平行六面体状的ZnO聚集体充当光散射层的研究还未见报道。同时，以金属有机框架材料充当界面调控层，可增强ZnO对酸碱的抗腐蚀性，进一步改善电池的整体性能。 Dye-sensitized solar cells have the advantages of low price, environmental friendliness, simple fabrication, and high conversion efficiency, and become the representative of the third generation of solar cells. Among the photoanode materials for dye-sensitized solar cells, ZnO has been widely studied because of its high electron mobility, easy-to-control morphology, and suitable energy band structure. In order to be able to absorb enough dyes, the photoanode material usually uses nano-ZnO, so that the electrode material has a certain light transmittance, which reduces the utilization of incident light and the overall performance of the battery. In order to improve the light collection efficiency of electrode materials, a light-scattering layer can be prepared on its surface, but the research on using parallelepiped ZnO aggregates as light-scattering layer has not been reported yet. At the same time, using metal-organic framework materials as the interface control layer can enhance the corrosion resistance of ZnO to acid and alkali, and further improve the overall performance of the battery.
