This work presents a comprehensive investigation of novel organic dyes MD‐1‐2 as active acid and base co‐sensitizers in dye‐sensitized solar cells (DSSCs), using well‐known Ru(II)‐based N3 dyes. These co‐sensitizers contain a triphenylamine ring as a donor scaffold linked with an electron‐withdrawing cyanopyridyl and cyano benzoic acid acceptor for MD‐1‐2. In this study, we demonstrated the significant impact of base dyes with pyridine anchoring units on the photovoltaic parameters of N3‐sensitized devices. This methodology takes advantage of the ability of carboxyl and pyridyl moieties to interact with the Brønsted acid and Lewis acid sites on TiO2 surfaces, respectively. By reducing competition between dyes for surface binding, dye packing density on the TiO2 is enhanced while electron recombination is minimized, leading to higher photovoltage. Furthermore, the influence of varying sensitizer/co‐sensitizer ratios was comprehensively studied. Outcomes showed devices made using co‐sensitizer MD‐1‐2 with sensitizer N3 at all relative concentrations surpassed those with only N3. Importantly, the co‐sensitized devices that were made utilizing 0.3 mM acid–base MD‐1 and N3 sensitizer had the greatest solar energy capacity. It had a power conversion efficiency of 10.35%, a short‐circuit current density of 20.01 mA·cm−2, and an open‐circuit voltage of 752 mV. The results provide fresh insight into optimizing devices to create DSSCs with improved efficiency by choosing acceptable co‐sensitizers at suitable concentrations.

“…Because of their construction and operation principle, dye-sensitized solar cells (DSSCs) can be easily adapted to the conditions imposed by the optimal operation of greenhouses. 4 Simplicity, low cost, and modeling of light absorption through dye selectivity, because the photosensitizers can be finely modified for wavelength-selective absorption, are the attractive advantages of DSSCs. 5–13 The choice of DSSC dyes in greenhouses can extend beyond energy generation and play a significant role in optimizing the plant growth conditions.…”

“…[23] Badawy et al synthesized hydrazonothiazole dyes as sensitizers for DSSCs in greenhouse applications which showed excellent long-term stability and impressive PCE of 8.85% with a current density ( J SC ) of 17.90 mA cm À2 . [24] Elmorsy et al presented a D-A type photosensitizer based on carbazole as a donor and thiazolidine-4-one as an acceptor and achieved an unexpected PCE of 9.55% (32% better than N719 dye sensitizer). [25] Previous research suggests the utilization of vat dyes such as Indigo, [26] Safranin O, [27] perylene 3,4,9,10-tetracarboxylic dianhydride, [28] and anthraquinone [29] dyes in the field of DSSCs, and substantial PCEs were achieved in several cases.…”

The greatest candidates for organic dyes that exhibit redox activities are vat dyes. Polymers based on vat dyes become effective sensitizer material for dye‐sensitized solar cells (DSSCs) because of their higher absorption coefficient and redox properties by reducing the polymeric film thickness. Herein, an ionic liquid (IL)‐supported D–A type conjugated polyimide sensitizer based on vat dye Congo red and pyromellitic dianhydride is synthesized via condensation polymerization technique. This polymeric material is doped with BF3 and supported with a minimal quantity of IL for better conductivity results and interface creation. The synthesized polyimide shows altruistic oxidoreduction properties with a narrow bandgap of 1.96 eV. Additionally, it comprises conjugated electrons having a backbone system that shows good electrical conductivity (>10−4 S cm−1) and becomes a semiconducting material. To determine the photovoltaic characteristics of the synthesized polymeric material, electrode fabrication and DSSC are carried out. The estimated photovoltaic characteristics are Jsc = 0.2324 mA cm−2, fill factor = 0.6906, and Voc = 0.2380 V. The power conversion efficiency of the device is obtained at 0.04%. The film‐forming property of polymeric sensitizer can reduce electron passivation in the cell. These observed properties of polymeric sensitizer material hardly claim their suitability for DSSCs applications.
