Forefront characterization techniques for renewable energy technologies
Currently, many renewable energy (green) technologies (including photovoltaic (PV) panels, LEDs for efficient lighting, fuel cells, and batteries) are hindered by a variety of material defects that limit their efficiency below theoretical maximums. The ability to accurately and rapidly characterize these defects is a key technical challenge needed to make an array of green technologies more efficient, thus more economically competitive with conventional technology. Broadly speaking, my research interests center on developing cutting edge characterization techniques for renewable energy technologies, especially photovoltaic cells and LEDs. Currently, research efforts center on camera-based imaging of electroluminescence to fully characterize material defects limiting device performance in CIGS PV cells.
