“…[163,164] Along these lines, sustainable and/or bio-based dyes include proteins and natural dyes. [165][166][167] Their device performance, implementation and limitations will be summarized in Section 5.3. As far as the electrolyte is concerned, liquid, quasi-solid, and solid electrolytes based on several redox species have been investigated.…”

“…Proteins: In 2015, Molaeirad and Rezaeian immobilized for the first time a layer of bR onto a ZnO film and successfully built PV devices within DSSC concept. [165] In detail, they used a dip coating film deposition to sensitize the photoanonde with a monolayer of bR (Figure 11). The device was closed with a Pt-based counter electrode and filled the space between the two electrodes with iodine liquid electrolyte.…”

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...

“…Of particular interest to biotechnological applications is the well-characterized bacteriorhodopsin (bR), first isolated from Halobacterium salinarum, which functions as light-driven proton pump [133][134][135]. Both wild-type and mutant strains of bacteriorhodopsin have been used as light absorbers in dye-sensitized solar cells based on TiO2 [136][137][138] and ZnO [139] mesoporous semiconductor surfaces. In such applications, the visible light absorption (λmax = 568 nm) and good photochemical stability of the bound retinal cofactor make bR a good photosensitizer.…”

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.

“…This changes in potential map of bR most likely results in better attachment of bR to exposed oxygen atoms of anatase surface [28]. is an appropriate substrate to immobilize bR, a low IEP protein, by electrostatic interactions with high binding stability [46]. On the other hand, loading the nanostructured photoelectrode with more than one layer of bR can significantly decrease the charge transfer rate in the TiO2/bR interface [22].…”
