Nature provides us the most effective way of harnessing solar energy, that is photosynthesis. The investigation of natural photosynthetic components integrated electrodes for the construction of photoelectrochemical cells has attracted more and more attention. However, the efficiency of assembled systems still be plagued by the complex and unclear electron transfer process. In this research, thylakoid membrane was integrated with graphene materials for the construction of photoelectrochemical cells and photocurrent of mediated electron transfer was investigated. Moreover, the main route of electron transfer within the composite film modified electrode was discussed. The functional groups and structural support of graphene oxide could increase local mediator concentration and accelerate diffusional mass transport, thus enhancing the photocurrent density.
