Organic semiconductors are studied for their potential in next-generation optoelectronic devices. While they have many advantages over inorganic materials such as silicon, their material properties are still not well understood compared to inorganic materials. Research focuses on exciton and charge carrier dynamics in organic materials and organic/inorganic hybrid systems. Resolving the interfacial state’s problem and elucidating the characteristics of excitons and charge carriers represent critical steps to achieve efficient organic-based devices.
