Provided herein are systems and methods for generating photocurrent and systems and methods for generating hydrogen. The systems comprise (a) isolated biological photosystem II (PSII) complexes; (b) an anode selected from the group consisting of graphite anode, glassy carbon anode, and FTO anode, wherein the PSII complexes are deposited onto the anode; (c) a source of red or white light, wherein red or white light illumination of the PSII complexes deposited on the anode generates a photoresponse comprising a photocurrent; (d) a working solution; and (e) a cathode. The methods comprise (a) isolating biological photosystem II (PSII) complexes; (b) providing an anode selected from the group consisting of a graphite anode, a glassy carbon anode, and an FTO anode, wherein the PSII complexes are deposited onto the anode; (c) providing a working solution; (d) providing a cathode; and (e) illuminating with red or white light the PSII complexes deposited on the anode, wherein red or white light illumination of PS II complexes generates a photoresponse comprising a photocurrent.
