“…I − /I 3 − has been the redox couple of choice in DSSCs due to comparatively high efficiencies and fast dye regeneration . Photoconversion efficiencies well beyond 11 % were realized with iodide‐based electrolytes in liquid‐state devices, while for solid‐state electrolytes iodide maximum photoconversion efficiencies reached into a range from 7 % to 8 % . The number of drawbacks, which are linked to the use of iodide electrolytes in DSSCs, fueled the research regarding alternative redox couples: competitive light absorption with the photosensitizer, the corrosive nature of the electrolyte, as well as the low redox potential of 0.4 V vs NHE limiting the V OC of a device.…”

To gather a comprehensive understanding of copper complexes as redox couples in dye-sensitized solar cells (DSSCs), a series of copper complexes were synthesized and thoroughly characterized. Characterization was undertaken using an arsenal of spectroscopic techniques, including steady-state spectroscopy, electrochemical and spectroelectrochemical assays, currentvoltage measurements, electrochemical impedance spectroscopy (EIS), and transient absorption spectroscopy (TAS).Starting from a homoleptic copper complex featuring two bathocuproine ligands and replacing one of them by either another N-or a P-coordinating ligand, a clear relationship between ligand size, on one hand, and charge transport, recombination as well as effective regeneration of the sensitizer, on the other hand, was established. With this information in hand, the future targeted synthesis of copper complexes to achieve maximum device performance may be achieved.

“…As far as the electrolyte is concerned, it has become increasingly important to find an alternative to liquid electrolytes. Such is the case of using binary salts and tetrahexylammonium iodide in gel form in reference [73]. These investigations bring DSSCs closer to achieving a solid or, at least, a quasi-solid version.…”

Human beings are attempting to take advantage of renewable natural resources by using solar cells. These devices take the sun’s radiation and convert it into electrical energy. The issue with traditional silicon-based solar cells is their manufacturing costs and environmental problems. For this reason, alternatives have been developed within the solar cell field. One of these alternatives is the dye-sensitized solar cell (DSSC), also known as Grätzel solar cells. DSSCs are a type of solar cell that mimics photosynthesis. They have a photoanode, which is formed by a semiconductor film sensitized with a dye. Some of their advantages include low-cost manufacturing, eco-friendly materials use, and suitability for most environments. This review discusses four important aspects, with two related to the dye, which can be natural or synthetic. Herein, only natural dyes and their extraction methods were selected. On the other hand, this paper discusses the nanostructures used for DSSCs, the TiO2 nanostructure being the most reported; it recently reached an efficiency level of 10.3%. Finally, a review on the novelties in DSSCs technology is presented, where it is observed that the use of Catrin protein (cow brain) shows 1.45% of efficiency, which is significantly lower if compared to Ag nanoparticles doped with graphene that report 9.9% efficiency.

“…Unfortunately, quasi-solid DSSCs have not shown a better PCE value than liquid DSSCs, with PCE values ranging from 4% to 5 % [44]. A few have a PEC value of 7%, such as a PAN (polyacrylonitrile)-based DSSC combined with RbI and tetrahexylammonium iodide salt developed by Bandara et al [47].…”
