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.

已经进行了材料设计和新型透明导电膜的优化，以构建无ITO和高效的光伏细胞。制备由Li掺杂的氧化锌（ZnO）纳米棒阵列制成的无机透明导电膜，在ZnO表面上低分子有机染料的单分子固定，以及在调查的（3-甲基二烯）的指导聚合物中（p3H）组合中混合有机光伏组合的组装和评估。已经证实，通过提高电流密度和开路电压，LI兴奋剂的功率转化效率（PCE）提高了1。5倍。还发现，高度定向的单分子层的引入带来了两倍的开路电压，并在近红外区域引入了具有大分子吸收系数的染料，导致当前密度的4倍增长。与分散状态相比，还设计并成功地形成了由卟啉/富勒烯和氧化钛组成的ZnO，而且由卟啉/富勒烯和P3HT或氧化钛组成的一维纳米夹与形成高效的载流子通行证。
