Abstract

Corona poling effects on optical and structural characteristics of zinc oxide (ZnO) thin films prepared by sol-gel spin coating technique were investigated. Atomic force microscope study showed the formation of pyramidal grains structure on the Corona-treated surface. The green-yellow photoluminescence peak centered at 2.36 eV and correlated to the antisite oxygen O defect, was found to decrease. X-ray diffraction patterns demonstrated that the Corona treatment enhanced the polycrystalline nature and increased the grain sizes of the ZnO thin films, which was also beneficial for electron transport. The role of the surface roughness of the ZnO thin film as electron transport layer in determining the photovoltaic effect of the inverted solar cells (ISCs) was examined by fabricating ISCs based on P3HT/PCBM. The power conversion efficiency (PCE) obtained from these fabricated ISCs increased from 3.05 to 3.34%.

摘要

电晕处理对旋涂溶胶-凝胶法制备的氧化锌 (ZnO) 薄膜的光学和结构特性的影响进行了研究。原子力显微镜研究表明，在电晕处理后的表面上形成了金字塔形晶粒结构。绿光-黄光电致发光峰位于 2.36 eV 处，与反位氧 O 缺陷有关，发现其强度降低。X 射线衍射图谱表明，电晕处理增强了 ZnO 薄膜的多晶性质，并增加了晶粒尺寸，这也有利于电子输运。通过制备基于 P3HT/PCBM 的倒置太阳能电池 (ISCs)，研究了 ZnO 薄膜的表面粗糙度作为电子输运层对光伏效应的影响。从这些制备的 ISCs 中获得的功率转换效率 (PCE) 从 3.05%提高到 3.34%。
