Photosynthesis-inspired bifunctional energy-harvesting devices that convert light and salinity gradients into electricity

Abstract

Inspired by the bifunctional utilization of light energy and a proton gradient in photosynthesis, we proposed conceptually an energy-harvesting device that is capable of converting light and a salinity gradient into electricity simultaneously. Our bioinspired concept provided a potential opportunity to harvest multiple renewable energies and maximize the overall power output.
