Research Interests

​Currently I am interested in using the drift-diffusion and Kinetic Monte Carlo method to simulate the microscopic transport and recombination behaviors of charge carriers in organic semiconductors, and reveal their influence on macroscopic device efficiency of organic photovoltaic devices.
