| Research Abstract |
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.
