Materials design and optimization of novel transparent conducting film for construction of ITO-free and highly efficient photovoltaic cells have been performed. Preparation of inorganic transparent conducting film made of Li-doped zinc oxide(ZnO) nanorod arrays, single molecular fixation of low-molecular organic dyes on the surface of the ZnO, and assembly and evaluation of hybrid organic photovoltaics in the combination with conducting polymer of poly(3-hexylthiophene)(P3HT) have been investigated. It was confirmed that the Li-doping resulted 1. 5 times improvement of power conversion efficiency(PCE) through the enhancement of the current density and the open circuit voltage. It was also found that introduction of the highly oriented single molecular layer brought doubled open circuit voltage and introduction of the dye with large molecular absorption coefficient in the near infrared region caused 4 times increment of the current density. Not only ZnO, but one-dimensional nanoassemblies composed of porphyrin/fullerene and P3HT or titanium oxide have also been designed and succeeded to form highly efficient carrier pass as compared with that of the dispersed state.

已经进行了新型透明导电薄膜的材料设计和优化，用于构建无 ITO 的高效光伏电池。掺锂氧化锌（ZnO）纳米棒阵列无机透明导电薄膜的制备、低分子有机染料在ZnO表面的单分子固定以及与导电聚合物结合的杂化有机光伏电池的组装与评价聚（3-己基噻吩）（P3HT）已被研究。证实Li掺杂通过提高电流密度和开路电压使功率转换效率（PCE）提高1. 5倍。研究还发现，高取向单分子层的引入使开路电压增加了一倍，而近红外区分子吸收系数大的染料的引入使电流密度增加了4倍。不仅是ZnO，由卟啉/富勒烯和P3HT或氧化钛组成的一维纳米组件也已被设计并成功形成与分散状态相比的高效载流子通道。
