Charge generation and carrier diffusion in organic solar cells
WONG Kam Sing
To study the photo-generated carrier dynamics and carrier diffusion length in organic solar cells. Time-resolved photoluminescence and femtosecond pump-probe technique will be used to investigate the carrier diffusion, transport and recombination dynamics in organic solar cell materials. Photo-CELIV will also be used to measure the carrier mobility in real organic solar cells
UROP1000 UROP1100 UROP2100
Measurement and analysis of the data. Good background in semiconductor physics and some experience in optics and spectroscopy technique will be an advantage.
Applicant's Learning Objectives:
Learn new experimental technique, data analysis and simulation. Better understanding how solar cell work
