Welcome to Noguchi group!


Our laboratory studies the physical properties and device physics of organic semiconductor devices, including organic light-emitting diodes, organic photovoltaics, and light-emitting electrochemical cells. In particular, we focus on the relationship between interfacial phenomena such as charge injection, accumulation, recombination, and separation, and microscopic physical processes such as exciton dynamics, molecular orientation, and polarization. Using electrical and optical measurement techniques developed in our laboratory, we seek to understand what is happening inside operating devices and to establish design principles for high-performance and highly functional organic semiconductor devices.
