Polycrystalline Thin-Film Photovoltaics

Cadmium Telluride (CdTe)

We develop processes and a range of materials for CdTe photovoltaic (PV) devices. Our work includes advanced characterization, fundamental theory, and collaboration with university and industry partners. Our objectives are to improve CdTe PV performance, reduce costs, and advance fundamental knowledge. We study both single-crystal materials for fundamental research, and polycrystalline devices that are industrially relevant in the near term.

Copper Indium Gallium Diselenide (CIGS)

We develop processes and materials related to thin-film polycrystalline PV devices, and our measurements and characterization work helps us gain a deeper understanding of these materials and devices. Our goal is to lower the manufacturing cost of CIGS PV products. Research projects tackle issues to improve CIGS processes and materials quality control, long-term stability and reliability of CIGS devices, and the search for new and alternative materials that can lead to a lower cost per watt.
