The biological process of photosynthesis was critical in catalyzing the oxygenation Earth’s atmosphere 2.5 billion years ago, changing course development life on Earth. Recently, fields applied and synthetic have utilized light-driven protein–pigment supercomplexes central to for photocatalytic production fuel other various valuable products. reaction center Photosystem I is particular interest due its high stability post-purification, non-geopolitical limitation, ability generate greatest...
In nature, solar energy is captured by different types of light harvesting protein-pigment complexes. Two these photoactivatable proteins are bacteriorhodopsin (bR), which utilizes a retinal moiety to function as proton pump, and photosystem I (PSI), uses chlorophyll antenna catalyze unidirectional electron transfer. Both PSI bR well characterized biochemically have been integrated into photovoltaic (PV) devices built from sustainable materials. some the best performing photosensitizers in...
Sustainable energy production is critical for meeting growing worldwide demands. Due to its stability and reduction potential, photosystem I (PSI) attractive as the photosensitizer in biophotovoltaic devices. Herein, we characterize aqueous organic solvent soluble synthetic bipyridine-based cobalt complexes redox mediators PSI-based biophotovoltaics applications. Cobalt-based are not destructive protein have appropriate midpoint potentials electron donation PSI. We report on PSI solvents...
Isolated proteins, especially membrane are susceptible to aggregation and activity loss after purification. For therapeutics biosensors usage, protein stability longevity important. It has been demonstrated that photosystem I (PSI) can be successfully integrated into biohybrid electronic devices take advantage of its strong light-driven reducing potential (-1.2V vs. the Standard Hydrogen Electrode). Most utilize PSI isolated in a nanosize detergent micelle, which is difficult visualize,...

Every solar cell in space is protected with Ce-doped coverglass whose main function to shield the against radiation of high energy particles. The minimum thickness 2-3 mils, which ultimately limits flexibility and weight ultra-light arrays. Furthermore, adhesion on a low throughput step assembly process. In this work, shielding required for different operating orbits, lifetime mission, hardness used studied. Ultra-light flexible alternatives allow low-cost array integration will be...
