Research Interests

Our research are focused on the fundamental studies of new quantum nanostructure based intermediate band solar cell and hot carrier solar cell. Meanwhile we aim to develop the techniques to drive the cost of the solar cell down while keeping their high efficiency. Our research interests include:

(1) Optical transition calculation using 8 band k∙p for quantum dot superlattice based intermediate band solar cell and hot carrier solar cell. Monte-Carlo simulation of photocarrier generation, recombination and transportation at high energy bands;
(2) Fabrication of ELO based thin film quantum dot solar cell and optical cavity simulation ;
(3) Development of novel approach for analysis of multijunction solar cell including internal luminescence coupling effect.


Keywords

Quantum dot, hot carrier, solar cell, carrier transportation, Monte-Carlo method.
