Abstract:
A water-oxygen-water photosynthetic bioelectrochemical cell (PBEC) comprising hybrid poly(fluorene-alt-phenylene) (PFP)/PSII-enriched membranes (BBY) photoanode and bilirubin oxidase (BOD) biocathode has been designed and fabricated. In the PBEC, water is split into oxygen, protons, and electrons through light-dependent reaction of PSII at the photoanode, and oxygen is converted into water catalyzed by BOD at the biocathode, forming the electronic circuit and generating current. At the photoanode, PFP can simultaneously accelerate the photosynthetic water oxidation and the electron transfer between BBY and electrode. Interestingly, the photocurrent density produced by PBEC after the introduction of PFP reaches 1.05 ± 0.01 μA/cm2, which is 2.5 times more than that of the BBY electrode, indicating that conjugated polymer can enhance the photoelectric response of PBEC.

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...
