High-Efficiency Photovoltaics

Sattelite floating above Earth's atmosphere with the sun in the background.

Researchers are developing new materials and device concepts for application to next-generation, high-efficiency, photovoltaic (solar) technologies. Interest lies in the development of solar cells for both terrestrial- and space-based applications.

Examples of renewable energy technologies based on photovoltaics include perovskite-based and hot-carrier solar cells.
