GALLIUM ARSENIDE PHOTOVOLTAICS

Ever thinner high-efficiency cells

Nature Energy volume 4, pages 726–727 (2019)Cite this article

Subjects

Ultrathin III–V solar cells are sought after for their relatively low cost and potential novel applications such as hot-carrier solar cells, but currently suffer from low power-conversion efficiency. Now, light-trapping nanostructures have been demonstrated to enable efficiency of 19.9% in a 205-nm-thick GaAs solar cell.
