Development of high-efficiency solar cells is one of the most important challenges in science as energy source for the next generation. We succeeded in induction of nanocolumnar morphology of tetrabenzoporphyrin, an organic semiconductor, on a polymer substrate coated with a solution-processed graphitic material having one-atom thickness. Dispersed graphitic flakes enabled us to form uniformly dispersed nanocolumnar structure, which can be utilized for increasing current density in organic photovoltaic devices.

开发高效太阳能电池是下一代能源科学中最重要的挑战之一。我们成功地在涂有单原子厚度的溶液处理石墨材料的聚合物基底上诱导了四苯并卟啉（一种有机半导体）的纳米柱形貌。分散的石墨片使我们能够形成均匀分散的纳米柱状结构，可用于增加有机光伏器件的电流密度。
