GALLIUM ARSENIDE PHOTOVOLTAICS

Ever thinner high-efficiency cells

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.
