“…[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.…”

“…Two years later, Montagni et al improved the performance of the red-pigment-based DSSCs through the usage of polysaccharide co-sensitizers, which helped in improving bonding/anchoring of xanthophylls pigments onto the TiO 2 surface due to the presence of extra hydroxyl groups. [167] Noteworthy, this class of carotenoids from Antarctic bacteria has not been employed as co-sensitizer with other natural dyes yet, e.g., chlorophylls, suggesting that further improvements are easily at hand.…”

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...

“…To broaden the comparison, we also assessed the efficiency values obtained with other types of cells that can accommodate biological photosensitizers, such as dye-sensitized solar cells (DSSCs). DSSCs incorporating pigments obtained from Antarctic bacteria demonstrated efficiencies of 0.008% [ 91 ] and 0.0332% [ 92 ]. When contrasting these efficiency values with those obtained from biosynthesized CIS QDs, the results suggest similar efficiencies, possibly indicating a slightly lower efficiency due to the organic nature of the CIS QDs.…”

In recent years, the utilization of extremophile microorganisms for the synthesis of metal nanoparticles, featuring enhanced properties and diverse compositions, has emerged as a sustainable strategy to generate high-quality nanomaterials with unique characteristics. Our study focuses on the biosynthesis of Cu-In-S (CIS) nanoparticles, which has garnered considerable attention in the past decade due to their low toxicity and versatile applications in biomedicine and solar cells. Despite this interest, there is a notable absence of reports on biological methods for CIS nanoparticle synthesis. In this research, three yeast species were isolated from soil samples in an extreme Antarctic environment—Union Glacier, Ellsworth Mountains. Among these isolates, Filobasidium stepposum demonstrated the capability to biosynthesize CIS nanoparticles when exposed to copper sulfate, indium chloride, glutathione, and cysteine. Subsequent purification and spectroscopic characterization confirmed the presence of characteristic absorbance and fluorescence peaks for CIS nanoparticles at 500 and 650 nm, respectively. Transmission electron microscopy analysis revealed the synthesis of monodisperse nanoparticles with a size range of 3–5 nm. Energy dispersive X-ray spectroscopy confirmed the composition of the nanoparticles, revealing the presence of copper, indium, and sulfur. The copper/indium ratio ranged from 0.15 to 0.27, depending on the reaction time. The biosynthesized CIS nanoparticles showed higher photostability than biomimetic nanoparticles and demonstrated successful application as photosensitizers in quantum dot-sensitized solar cells (QDSSC), achieving a conversion efficiency of up to 0.0247%. In summary, this work presents a cost-effective, straightforward, and environmentally friendly method for CIS nanoparticle synthesis. Furthermore, it constitutes the first documented instance of a biological procedure for producing these nanoparticles, opening avenues for the development of environmentally sustainable solar cells.

“…More details about the electronic processes occurring at the DSSCs are obtained by applying EIS techniques (Figure 7). As previously reported, the impedance registers are fitted via the use of equivalent circuits integrated for several elements [64][65][66][67]. Some particular parameters are useful in understanding the calculated efficiencies (displayed in Table 4):…”

This work aimed to show the possibility of applying anthocyanins extracted from blueberries following a straightforward path as potential impregnation dyes in dye-sensitized solar cells (DSSCs), particularly in the presence of co-adsorbents, such as silver nanoparticles, as an alternative in order to profit from large amounts of discarded fruits. Following a simple procedure, anthocyanins (mainly delphinidin-3-glucoside) were obtained from blueberries (Southern Highbush type). Complete characterization was carried out in order to prove the utility of delphinidin-3-glucoside as a sensitizer in DSSCs. The analyzed anthocyanin is suitable for sensitizing because of its high molar absorptivity values within the visible region of the light spectra, the adsorption ability to a FTO/TiO2 electrode (FTO, fluorine-doped tin oxide) as confirmed by Fourier transform infrared (FTIR) as well as thermogravimetry coupled to differential scanning calorimetry (TG-DSC), a potential oxidation value near 1 V, and adequate thermal as well as light stabilities. Moreover, the cell’s conversion efficiency is improved in the presence of silver nanoparticles, reaching 0.24% (nearly a 25% increase). The sum of all these characteristics points to the application of delphinidin-3-glucoside as a sensitizer in DSSCs, offering a technological use with potential interest for countries where agricultural production offers an abundant origin of extraction.
