Outline of Research at the Start

Perovskite photovoltaic has great potential of replacing silicon in becoming the next-generation solar cells material. In this project, I plan to utilize a new table top electron microscopic technique to study the degradation process in perovskite devices, to help us develop more durable solar cell.
