“…1 confirmed our hypothesis that the immobilized selfassembled APC trimers on a sensitized photoanode formed a multilayer with a non-specific orientation, similar to the findings from earlier reports [15][16][17]. Moreover, the very similar fluorescence emission spectra from the APC trimer complexes in solution and on TiO 2 both exhibited a fluorescence emission maximum at 660 nm with a shoulder at around 640 nm (Fig.…”

“…It is possible that electrostatic interactions, especially hydrogen bonds, which are strong noncovalent forces in biological systems through functional groups such as carbonyl, amide, or imidazole, especially in macromolecules, are responsible for the multilayer adsorption, as noted previously [5,15,18]. Previous reports suggested that photocurrent generation based on photoreaction center complexes (BR, PSI, and PSII) is a result of electron transfer and continuous re-reductions in solution, after charge separation originating from the initial photoexcitation [4,17,19]. However, as in antenna complexes, the photocurrent in this case was ascribed to the photoexcited trimer and subsequent electron transfer, as demonstrated in previous reports ( Supplementary Fig.…”

“…The obtained solar cell generated a photocurrent at a density of about 2 mA/cm 2 under illumination by a standard light intensity (clear sky at noon). The device demonstrated a considerable stability and retained activity under ambient conditions for at least 280 d (Ciesielski et al, 2010).…”

“…The devices developed based on the two and three layers generated photovoltage outputs of 0.330 and 0.386 V, respectively (Frolov et al, 2008). Hereafter, work on the development of solar cells based on multilayer structures of PS1 was continued (Ciesielski et al, 2010;Mershin et al, 2012). The suggested method did not require the use of photosystems isolated from mutated cyanobacteria, nor the use of a high vacuum, making it more economical and less time-consuming.…”

HIGHLIGHTSPhotosynthesis is a process which converts light energy into energy contained in the chemical bonds of organic compounds by photosynthetic pigments such as chlorophyll (Chl a, b, c, d, f) or bacteriochlorophyll. It occurs in phototrophic organisms, which include higher plants and many types of photosynthetic bacteria, including cyanobacteria. In the case of the oxygenic photosynthesis, water is a donor of both electrons and protons, and solar radiation serves as inexhaustible source of energy. Efficiency of energy conversion in the primary processes of photosynthesis is close to 100%. Therefore, for many years photosynthesis has attracted the attention of researchers and designers looking for alternative energy systems as one of the most efficient and eco-friendly pathways of energy conversion. The latest advances in the design of optimal solar cells include the creation of converters based on thylakoid membranes, photosystems, and whole cells of cyanobacteria immobilized on nanostructured electrode (gold nanoparticles, carbon nanotubes, nanoparticles of ZnO and TiO2). The mode of solar energy conversion in photosynthesis has a great potential as a source of renewable energy while it is sustainable and environmentally safety as well. Application of pigments such as Chl f and Chl d (unlike Chl a and Chl b), by absorbing the far-red and near infrared region of the spectrum (in the range 700-750 nm), will allow to increase the efficiency of such light transforming systems. This review article presents the last achievements in the field of energy photoconverters based on photosynthetic systems.

Application of technical developments in biology and vice versa or biological samples in technology led to the development of new types of functional, so-called "biohybrid" materials. These types of materials can be created at any level of the biological organization from molecules through tissues and organs to the individuals. Macromolecules and/or molecular complexes, membranes in biology, are inherently good representatives of nanosystems since they fall in the range usually called "nano." Nanohybrid materials provide the possibility to create functional bionanohybrid complexes which also led to new discipline called "nanobionics" in the literature and are considered as materials for the future. In this publication, the special characteristics of photosynthetic reaction center proteins, which are "nature's solar batteries," will be discussed in terms of their possible applications for creating functional molecular biohybrid materials.
