In the natural photosynthetic apparatus, photosynthetic reaction is coupled to biocatalytic transformations leading to CO2 fixation and O2 evolution. Although significant progress has been achieved in the integration of native photosystems with electrodes for light-to-electrical energy conversion, the conjugation of the photosystems to enzymes to yield photo-bioelectrocatalytic solar cells remains a challenge.

The photo-bioelectrochemical cells use glucose oxidase or glucose dehydrogenase and modified integrated electrodes that include the natural photosynthetic reaction center, known as photosystem I, conjugated to these enzymes...
