摘要/Abstract

摘要： 研究ITO/Metal/ITO（IMI）电极中金属层Cu和Ag及其厚度对电极光电性能的影响,结合霍尔测试、紫外分光光度计、原子力显微镜等分析金属层材料和厚度对IMI电极光电性能以及形貌的影响。通过优化金属层厚度,获得方阻分别为11.2 Ω/□和14.5 Ω/□且400~800 nm波长范围内平均透过率分别为93.9%和86.5%的ITO/Ag/ITO和ITO/Cu/ITO电极。将IAI和ICI电极作为正面电极应用于钙钛矿太阳电池,太阳电池的填充因子从62.5%提升至78.0%。IMI在短波段的较大反射率会导致电池短路电流密度低1~2 mA/cm²。当Cu层和Ag层的厚度分别为7.4 nm和6.4 nm时,钙钛矿太阳电池的效率达到最佳。

Abstract: In this work the influence of the metal layer Cu and Ag and their thickness on the opto-electrical performance of IMI contact is studied by using Hall measurement, ultraviolet spectrophotometer, Atomic Force Microscope, etc. By optimizing the thickness of intermediate metal layer, ITO/Ag/ITO （IAI） and ITO/Cu/ITO （ICI） contacts with sheet resistance of 11.2 and 14.5 Ω/□ and average transmittance of 93.9% and 86.5% were obtained in the wavelength range of 400-800 nm, respectively. The IAI and ICI layer are used as the front contact in perovskite solar cells. The fill factor of solar cells has increased from 62.5% to 78.0%, while the short-circuit current density is about 1-2 mA/cm; ²lower as compared to the reference cell on ITO contact. This is mainly due to the increased reflectance of IMI in the short wavelength. As the thickness of Cu layer and Ag layer is 7.4 and 6.4 nm, respectively, an optimum cell efficiency has been obtained.
