There is an urgent need to develop new technologies to convert solar energy into fuels or electricity for a sustainable circular economy, eventually contributing to carbon neutrality. In terms of electricity generation, a biological technology referring to as biophotovoltaics (BPV) or microbial solar cells represents the greenest route.
Furthermore, the photocurrent generated in a BPV system can be used to drive the hydrogen fuel production at the cathode 6, 8. Therefore, BPV offers a biological alternative for solar energy utilization. The BPV process can be divided into two stages, charging and discharging.
Another important aspect of regulating product distribution and selectivity of light-driven conversion of biomass to chemicals is the optimization of reaction conditions. The mineralization of glucose is obviously inhibited by adding a certain amount of acetonitrile in an aqueous solution (Zhou et al., 2017a).
McCormick, A. J. et al. Photosynthetic biofilms in pure culture harness solar energy in a mediatorless bio-photovoltaic cell (BPV) system. Energy Environ. Sci. 4, 4699–4709 (2011). Saper, G. et al. Live cyanobacteria produce photocurrent and hydrogen using both the respiratory and photosynthetic systems. Nat. Commun. 9, 2168 (2018).
A stable and sustainable energy supply is crucial for all life on the earth. As the most abundant and renewable energy source, solar energy can be utilized in the form of electricity through photovoltaics (PV) that are made of semiconductor materials 1, 2.
This reaction takes place in an enzyme known as photosystem II, and the recent determination of its structure has given strong hints of how nature uses solar energy to generate hydrogen and oxygen from water.
