“…This could be attributed to the intimate contact between PSII and electrodes and the high electron transportation efficiency of graphene. 35 The influence of applied bias potential on the resulting photocurrent is displayed in Figure 3c. The photocurrent of ITO-PEI-rGO/PSII is always higher than those of other two anodes upon the same bias potentials.…”

A new type of biohybrid photo-electrochemical cell was fabricated by layer-by-layer assembly of photosystem II and reduced graphene oxide. We demonstrate that the photocurrent in the direct electron transfer is enhanced about two fold with improved stability. The assembly strategy without any cross-linker or additional electron mediators makes the cell fabrication and operation much simpler as compared to previous approaches. This work may open new routes for the construction of solar energy conversion systems based on photoactive proteins and graphene materials.

“…Of course, this point of care leads to the generation of organic and hybrid inorganic/organicbased electronics. In respect to previously mentioned trend, LeBlanc and the co-workers [2,3] aligned with their earlier research, report articles which introduced a new bio-based material with interesting optoelectronic properties called photosystem I (PSI) pigment-protein complex.…”

The trends of using biological materials in electronic devices have made great developments in the last few years. Furthermore, the appealed cost features of organic semiconductors represent a bright lowcost, environment compatible, and efficient future for bio & nanotechnologies, especially Bio-organic solar cells which may consider as a noteworthy option for photovoltaic applications. Here, we report a novel single junction organic solar cell based on photosystem I pigment-protein complex. The complex which operated either as photosensitizer and charge generator compound, surprisingly. Photosystem I complexes were extracted from young spinach leaves and used as the active layer of the intended solidstate solar cell device, subsequently. After the characterization of the final cell, our photovoltaic system showed the current density of 3470 mA cm À2 which realizes as a notable approach in between photosystem-I based energy conversion systems.

“…pH-dependent poly(vinyl)imidazole osmium bis(2,2'-bipyridine)chloride redox polymer has also been utilized to improve electronic contact with PSI, yielding an electron transfer rate of up to 335±14 e − s −1 PS1 −1 [1]. A completely organic, optically transparent electrode can be constructed by using reduced graphene oxide (RGO) on which a functional plant PSI multilayer can be deposited [36].…”

The biological process of photosynthesis was critical in catalyzing the oxygenation of Earth’s atmosphere 2.5 billion years ago, changing the course of development of life on Earth. Recently, the fields of applied and synthetic photosynthesis have utilized the light-driven protein-pigment supercomplexes central to photosynthesis for the photocatalytic production of fuel and other various valuable products. The reaction center Photosystem I is of particular interest in applied photosynthesis due to its high stability post-purification, non-geopolitical limitation, and its ability to generate the greatest reducing power found in Nature. These remarkable properties have been harnessed for the photocatalytic production of a number of valuable products in the applied photosynthesis research field. These primarily include photocurrents and molecular hydrogen as fuels. The use of artificial reaction centers to generate substrates and reducing equivalents to drive non-photoactive enzymes for valuable product generation has been a long-standing area of interest of the synthetic photosynthesis research field. In this review, we cover advances in these areas and further speculate synthetic and applied photosynthesis as photocatalysts for the generation of valuable products.
