Polycrystalline Thin-Film Photovoltaics

NREL is applying its expertise and energy to the development of polycrystalline thin-film photovoltaics, including cadmium telluride and copper indium gallium diselenide solar cells.

Cadmium Telluride

We develop processes and a range of materials for cadmium telluride photovoltaic (PV) devices to improve performance, reduce costs, and advance fundamental knowledge.


Copper Indium Gallium Diselenide

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.
