| Research Abstract |
Systematic investigation of the electronic structure, doping level, transport properties of the solution processable organic-inorganic hybrid perovskites was performed. Design of the novel doping method and device construction including organic semiconductors was also examined. As for the tin-iodide system, the origin of the high conductivity was clarified by this study. As for the organic semiconductors, novel concept of doping at the contact interface was proposed, and the electronic state at the interface was studied.
