| Abstract: | Inspired by the light‐driven, cross‐membrane proton pump of biological systems, a photoelectric conversion system based on a smart‐gating, proton‐driven nanochannel is constructed. In this system, solar energy is the only source of cross‐membrane proton motive force that induces a diffusion potential and photocurrent flowing through the external circuit. Although the obtained photoelectric conversion performance is lower than that of conventional solid photovoltaic devices, it is believed that higher efficiencies can be generated by enhancing the protonation capacity of the photo‐acid molecules, optimizing the membrane, and synthesizing high‐performance photosensitive molecules. This type of facile and environmentally friendly photoelectric conversion has potential applications for future energy demands such as the production of power for in vivo medical devices. |
