“…This was, for example, nicely highlighted by Lorquin and collaborators with respect to the application of carotenoids. [388] Up to date, DSSCs sensitized with flavonoids have shown PCEs <1%, [389][390][391] mostly due to dye aggregation, electron recombination, and prominent undesired back electron transfer reactions. In 2017, Prabavathy et al introduced two algae-derived buffer layers to functionalize the TiO 2 -photoanode, improving the anchoring groups suitable for dye loading and the overall efficiency of the anthocyanin-based PVs.…”

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...

“…135 DSSCs sensitized by anthocyanin pigments showed efficiencies below 1%, with the exception of a few cases (Table 1, entry 13). 135,163,172,173 The generated IPCE does not exceed 20%, even if charge injection is usually very fast, due to problems related to dye aggregation, electron recombination with the oxidized sensitizer and electron recapture by the iodine/iodide electrolyte. In all of these examples, both the efficiency and stability of lab-scale DSSCs are highly affected by the temperature of the extracting solvent and its nature, 174,175 where mainly its polarity influences the solubility of the pigments.…”

Dye‐sensitized solar cells (DSSCs) have turned a new horizon in energy research due to their widespread exploration over two decades by improving efficiency, cost‐effectiveness, and easy process than inorganic‐based solar cells. The major challenges are metal complexes on designing the cells and sustainability implications for further rapid expansion due to its toxicity. To overcome the problems associated with metal complexes, the dyes are extracted from bionatural sources such as flowers, fruits, barks, petals, roots, leaves, and beans of plants. These organic dyes are being nontoxic, cost‐effective, abundant, environmentally friendly, and easy to extract, which is made them extensively applicable for DSSC. Through this review, readers may get an idea about the effect in the efficiency of the solar cell by applying variable semiconductors, effects of solvents, variable light‐harvesting pigments, types of electrolytes, and modification of counter electrodes by certain polymeric materials or nanomaterials. Furthermore, the effects of methodology, processing temperature, and pH of the medium during synthesis on solar cell parameters, such as the efficiency of DSSC, are critically analyzed which are reported by other researchers.
