研究领域

I am researching metal oxide substrates and semiconductor quantum dots in order to elucidate the physical basis for improving the photoelectric conversion efficiency of quantum dot solar cells. metal oxide electrode is to function as an n-type semiconductor and to smoothly transport electrons generated by a sensitizer such as quantum dots. The characteristics of solar cells vary greatly depending on the structure of the metal oxide electrode, the type of crystal, and the like . It plays a role of absorbing light and generating carriers in the quantum dot solar cell. Since it has different characteristics from bulk semiconductors, it is expected to be applied to next-generation solar cells. Quantum dot solar cell A device that combines the above two, and has the function of converting light into electricity.At the current stage, the photoelectric conversion efficiency is low, but it has the potential to solve the world's energy problems. Dynamics of Photoexcited Carriers Charge separation and recombination dynamics of photoexcited carriers inside a solar cell exposed to light will be clarified by transient absorption measurements, a type of laser spectroscopy. View research details　 Research facilities Various measuring devices are used to elucidate the basic physical properties of solar cells from various angles. We have a wide variety of research facilities, which contribute greatly to basic research on solar cells.
