Electron Transfer/Transport Phenomena in Optoelectronic Devices
Physics of electron transfer/transport phenomena in devices such as solar cells, LEDs and photocatalysts
The course is designed for PhD students who are involved in research on optoelectronic devices. In particular we plan to go into details of physics of solar cells, LEDs, photocatalysts and solar hydrogen devices. Solar cells, photocatalyst and photoelectrochemical devices are mainly based on semiconductors that absorb photons, and the photo excited electrons and holes are transferred at the interfaces to an external electrical load, or used to initiate photo-induced reactions. In LEDs, the electrons and holes are electrically injected from the interfaces into a semiconductor, which consequently produce light by recombination. All these devices obey a similar physics, which is mainly on the relative position of energy levels and electron transfer processes at the interfaces.
