我们开发了一种构建分子光伏器件的新策略，其中卟啉和富勒烯作为构建块，通过自组装过程组织成纳米结构的人工光合系统。高效的光合作用能量和电子转移过程发生在金和铟锡氧化物（ITO）电极上，这些电极被自组装的单层卟啉-富勒烯连接系统修饰。卟啉和富勒烯也被一步一步地组装在纳米结构半导体电极上，形成大而均匀的簇，表现出接近1%的高功率转换效率。这些结果将为供体-受体型分子组装体的设计提供有价值的信息，这些分子组装体可以用于构建高效的光伏器件。
We have developed a new strategy for the construction of molecular photovoltaic devices where the porphyrins and fullerenes employed as building blocks are organized into nanostructured artificial photosynthetic systems by self-assembly processes highly efficient photosynthetic energy- and electron-transfer processes take place at gold and indium tin oxode (ITO) electrodes modified with self-assembled monolayers of porphyrin- of fullerene linked systems. Porphyrins and fullerenes have also been assembled step by step to make large and uniform clusters on nanostructured semiconductor electrodes which exhibit a high power-conversion efficiency of close to 1%. These results will provide valuable information on the design of donor-acceptor-type molecular assembles that can be tailored to construct highly efficient photovoltaic devices.
