“…However, current designs still function well below the internal quantum efficiency shown for PSI and photosynthetic charge separation in general, 9,14 suggesting room for device improvement. There are many different approaches being studied for the improvement of PSI-based biohybrid devices, including improving the unidirectionality of deposited PSI on electrodes, 15,16 improvement of the optical cross-section of PSI to increase light harvesting capabilities, 17,18 and interest in creation of solid-state devices [19][20][21] A key area of improvement is in PSI reduction rates to help increase dye regeneration rates. Reduction of T. elongatus PSI by its native biological redox mediator, the one-electron shuttle protein cytochrome c 6 , has (1) PSI absorbs a photon, (2) which then promotes the special chlorophyll pair PSI-P700 to an excited state.…”

The ever-increasing world energy demand drives the need for new and sustainable renewable fuel to mitigate problems associated with greenhouse gas emissions such as climate change. This helps in the development toward decarbonisation. Thus, in recent years, hydrogen has been seen as a promising candidate in global renewable energy agendas, where the production of biohydrogen gains more attention compared with fossil-based hydrogen. In this review, biohydrogen production using organic waste materials through fermentation, biophotolysis, microbial electrolysis cell and gasification are discussed and analysed from a technological perspective. The main focus herein is to summarise and criticise through bibliometric analysis and put forward the guidelines for the potential future routes of biohydrogen production from biomass and especially organic waste materials. This research review claims that substantial efforts currently and, in the future, should focus on biohydrogen production from integrated technology of processes of (i) dark and photofermentation, (ii) microbial electrolysis cell (MEC) and (iii) gasification of combined different biowastes. Furthermore, bibliometric mapping shows that hydrogen production from biomethanol and the modelling process are growing areas in the biohydrogen research that lead to zero-carbon energy soon.

“…The coupling of approximately 30 ATTO 590 dye molecules to PSI increased the oxygen consumption activity of PSI by over 4-fold, and the addition of Lumogen Red allowed for greater energy transfer to PSI via Förster resonance energy transfer. Expanding the light harvesting capabilities of PSI through conjugation of dyes [7,12] is likely to be an area of further focus for improving outputs of future reaction center-based biohybrid devices.…”

“…Further, while the quantum efficiency of PSI's photoinduced electron generation approaches 100%, a report by Applegate found a quantum yield of 10-15% when photoexcitation energy between 400-700 nm was assessed [105]. In attempts to improve this quantum yield, Nagakawa et al utilized the addition of an artificial light harvesting dye, Lumogen Red, to improve the wavelengths of light available for PSI photocatalytic activity and saw large improvements over the non-dye modified PSI-Pt constructs [12]. Utilizing a different strategy to improve H2 yields by reducing the light harvesting chlorophyll pigments in Chlamydomonas reinhardtii 5-6 fold yielded approximately 2-5 fold increases in H2 production depending on the exact mutant strain studied [106].…”

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.
