“…Efforts have been already done in this direction, especially thanks to the DSSC concept, and the reader is invited to have a look at Section 5 and these dedicated reviews. [56,59,60,229] With regard to photosystem protein complexes, the standard extraction process is applied directly to the leaves. A homogenization step in a buffer solution leads to a slurry that is purified through centrifugation and filtration.…”

conditions. This makes difficult to further reduce the cost of electricity production. [7,8] Furthermore, although solar energy is a renewable source, it does not mean that any kind of photovoltaics (PV) is sustainable. For instance, silicon is an essential material in electronics and solar industries and, up to date, is irreplaceable. Despite its abundancy in Earth's crust, it is for the vast majority (80%) present as ferrosilicon, whose purification is expensive and highly pollutant. The production of 1 ton of silicon requires 6 tons of raw materials, almost 3 tons of Quartz, 1.5 tons of reducing agents, 1.5 tons of wood and 13 000 kWh of energy. [9,10] Therefore, in 2014 the EU commission included silicon metal in the critical raw material (CRM) list. [11] In this context, the third generation PV has reborn, offering cost-effective and efficient CRM-free devices with a lower reliance on the incident angle of light and integration in smart-end applications, like flexible and wearable devices, [12][13][14] fully transparent solar cells and windows, [15,16] and biocompatible devices. [17][18][19] The leading third generation SCs are organic solar cells (OSCs), [20][21][22] perovskite solar cells (PSCs), [23][24][25][26][27] and dye-sensitized solar cells (DSSCs). [28][29][30] Despite their versatile applications and high performances, sustainability still represents a major issue toward becoming an ideal energy technology in the mid-long term future. Among others, fullerene-based materials are toxic, [31] indium tin oxide (ITO) is brittle, chemically unstable, and expensive due to limited indium sources on Earth's crust. [32,33] Cobalt is also listed as CRM, [11] while cadmium, selenium, lead and ruthenium are toxic materials. [34,35] With regard to flexible devices, polyethylene terephthalate (PET) is the standard substrate; though its environmental footprint is critical and its nonbiodegradable properties lead to harmful effects in living organisms. [36] This has fueled a strong cooperation among the fields of engineering, biology, chemistry, and physics to discover new strategies for cost-effectiveness preparation and implementation of bio-derived materials in highly performing PVs.In general, this cooperation constitutes a part of the emerging and multidisciplinary field of biophotonics, [37] which involves biomedical optics, [38] living light, [39][40][41] biomimetic, biomaterials and bioengineered compounds, as well as fabrication/implementation methods applied to optoelectronics [42] and photonics, [43] among others. For instance, artificial lightning and biology have been recently merged with the implementation of cellulose, chitosan, silk, and fluorescent proteins as Accomplishing sustainability in optoelectronics, in general, and photovoltaics (PV), in particular, represents a crucial milestone in green photonics. Third generation PV technologies, such as organic solar cells (OSCs), perovskite solar cells (PSCs), and dye-sensitized solar cells (DSSCs) have reached a mature age and are slowly making thei...

“…The most promising direction of using BR at present is the development of materials for optical processing and data storage [1]. At the same time, this material at the molecular level has a number of properties that can be effectively used in security, encryption, and information protection systems [10]. The technology of obtaining the material itself is environmentally friendly while the resources are practically inexhaustible.…”

“…Bacteriorhodopsin (BR), one of the transmembrane protein complexes of halophilic microorganisms, can rightly be considered a pioneer and the most prominent representative of this trend. The possibilities of applied use of BR are impressive: optical recording with ultrahigh densities [1], switching of optical signals [2], photoelectric immunosensors [3], nonlinear optoelectronic elements [4], nanofluidics [5,6], alternative energy [7][8][9], information protection [10], etc. The advantages of BRbased materials include high resolution and photosensitivity, almost unlimited aperture and reversibility, significant photochromic displacement and percentage of color change, long service life.…”

The object of this study is the processes of interaction of fragments of purple membranes with certain chemicals, which affect the photochromic properties of bacteriorhodopsin films. This paper considers the possibility of modifying the properties of bacteriorhodopsin films by changing their chemical composition, which will make it possible to use such films to protect information. For this purpose, it has been determined which optical properties of bacteriorhodopsin are most important for its use in the field of information protection; films were made using various chemicals as impurities. It was shown that the introduction of impurities does not affect the absorption spectrum of bacteriorhodopsin, which indicates that it retains its properties. It has been established that impurity substances are evenly distributed in films. By studying the dynamics of photoinduced changes in films with different concentrations of chemical components, the effect of chemical modification on the photocycle of bacteriorhodopsin and the properties of film structures based on it was studied. Based on the results of experimental studies, it was found that by changing the chemical composition of films, it is possible to change the time of storage of the information recorded on them in the range from several to hundreds of seconds continuously. The sensitometric sensitivity of film structures also depends on the chemical composition and can vary in the range from 3.9·10–3 to 54·10–3 m2/J. At the same time, chemical modification is simpler from a technological point and cheaper from a financial point of view compared to other methods that make it possible to achieve similar results. The reported results suggest that chemically modified films based on bacteriorhodopsin have great potential for practical application in the field of information protection and access control

“…Some photosensitive biological materials, such as bacteria and cells, have been used to realize the effective transformation of environmental information into electrical signals based on the electrophysiological response under external stimulation. Moreover, by integrating biological materials with artificial electronic systems, various bio-syncretic sensing systems have demonstrated effective environment sensing [ 5 , 6 ]. Regarding intelligence, distinct neural networks derived from human pluripotent stem cells or isolated from the brain tissue of rats have been cultured in vitro and were combined with silicon computing systems with microelectrode array (MEA) chips to form a bio-syncretic intelligence controller.…”
