Outline of Final Research Achievements

The improvement of power conversion efficiency of organic solar cells are important problem for its practical application. The electronic structure of organic molecules in the organic solar cells is a crucial information to understand the photo current generation in organic solar cells. In this research, we studied a measurement method for the electronic state of organic molecules under operating condition of organic solar cells. By using the photoelectron spectroscopy under light irradiation and the electroabsorption spectroscopy under irradiation with white light, a change in the electronic states of the organic thin film caused by the light irradiation effect was observed. A fabrication method of semitransparent organic solar cells, which is suitable for the elecrtoabsorption method, was established. Furthermore, it was found that a lead halide perovskite film was able to fabricate by the vacuum deposition method using the perovskite single crystal as a deposition source.
