| Outline of Final Research Achievements |
Recent years have witnessed extensive research for the development of electronic devices such as solar cells, thermal electrical conversion devices, and light-emitting devices comprising organic and organic-inorganic hybrid materials. Particularly, organic and organic-inorganic hybrid solar cells exhibit potential advantages like low manufacturing cost, low weight, and mechanical flexibility. These solar cells typically contain two electrodes and one photoactive layer. The photoactive layer is composed of bulk heterostructures of a p-type semiconducting material as the electron donor and an n-type semiconducting material as the electron acceptor. Hence, morphology control of functional layers is important for high performance. In this viewpoint, I described the effect of the morphology control of nanophase separation structures in the photoactive layer of organic thin-film solar cells and organic-inorganic hybrid thin-film solar cells in this research.
