“…The performance of the second type is better than the first, but it is disadvantaged by its high cost and complex preparation methods 21 – 23 . In order to take advantage of both types, the co-sensitization process, which is the use of different types of p; dyes in the same preparation, was used in this application 24 – 28 .…”

We report on the synthesis and characterization of six novel 2,2′-bithiophene-based organic compounds (3a–c and 5a–c) that are designed to serve as co-sensitizers for dye-sensitized solar cells (DSSCs) based on TiO2. The compounds are linked to various donor and acceptor groups, and we confirm their chemical structures through spectral analyses. Our focus is on enhancing the performance of metal based N3, and the compounds were designed to operate at the nanoscale. We performed absorption and fluorescence emission measurements in dimethylformamide (DMF), where one of our compounds 5a exhibited the longest maximum absorption and maximum emission wavelengths, indicating the significant impact of the para methoxy group as a strong electron-donating group. Our dyes 5a + N3 (η = 7.42%) and 5c + N3 (η = 6.57%) outperformed N3 (η = 6.16%) alone, where the values of short current density (JSC) and open circuit voltage (VOC) for these two systems also improved. We also investigated the charge transfer resistance at the TiO2/dye/electrolyte interface using electrochemical impedance spectroscopy (EIS), which is important in the context of nanotechnology. According to the Nyquist plot, the 5a + N3 cocktail exhibited the lowest recombination rate, resulting in the highest VOC. Our theoretical calculations based on density functional theory (DFT) are also in agreement with the experimental process. These findings suggest that our compounds have great potential as efficient DSSC co-sensitizers. This study provides valuable insights into the design and synthesis of new organic compounds for use as co-sensitizers in DSSCs based on TiO2 and highlights the potential of these compounds for use in efficient solar energy conversion.

“…Several di-anchoring organic dyes designed and synthesized for use in DSSCs have demonstrated better cell performance than mono-anchoring D–π–A sensitizers, with an improved photocurrent due to the extension of the π-conjugated system and the increased molar extinction coefficient. 10 Because of its high optoelectronic efficiency, high conductivity potential, and high stability, 11 using furan and phenyl as donors is also generally accepted as a good way to improve the chemical, electrical, spectroscopic, and overall stability of the particles that will likely be made. In recent scientific literature, numerous dyes with multiple anchoring moieties were reported.…”
