Photosystem II ( PSII ) is a photoactive protein that can drive water oxidation under light irradiation. Recently, PSII has been broadly investigated with the high demand on the bioenergy. Here, we demonstrate a facile approach for the fabrication of a photoactive electrode by the integration of PSII with quantum dots ( QDs )/polyelectrolyte multilayers. The assembled QDs and PSII film with a polyelectrolyte based substrate via layer‐by‐layer assembly can remain the photoactivity of the PSII and broaden the absorption spectrum of PSII to produce a high photocurrent yield. The co‐assembly exhibits an obviously enhanced photocurrent under UV light irradiation. The proposed strategy can be considered for the reference and usage of PSII toward the solar energy conversion.
