Electron Transfer/Transport Phenomena in Optoelectronic Devices

Physics of electron transfer/transport phenomena in devices such as solar cells, LEDs and photocatalysts

PhD Course
2nd semester, 1391-92
Schedule: Sunday 08:30-10:30, Monday 10:30-12:30
Place: Physics Department, Otagh Shora (room 513)
Texts and projects: The students should refer to the course page in cw.sharif.edu (Choose Physics Department from the left and then choose the course)

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.
