Summary: The design and synthesis of two novel D-A dyes cTPAPh-NO2 and cTPABT-PyCN2 were reported, and their photophysical and electrochemical properties were investigated. The attachment of carboxyl groups reduced the light harvesting and intramolecular charge separation ability of cTPAPh-NO2. In contrast, cTPABT-PyCN2 exhibited weak fluorescence and efficient intramolecular charge separation characteristics. These dyes showed promising potential as p-type sensitizers with effective charge separation characteristics in dye-sensitized solar cells.

Summary: This study introduces five new bithienylnicotinonitrile-based organic dyes (coded GA-1-5) designed for use in dye-sensitized solar cells (DSSCs). The researchers conducted a detailed analysis of the dyes' characteristics and found that they exhibit intense UV-vis absorption and high molar extinction coefficients, making them ideal for use in DSSCs. When tested, devices co-sensitized with the dyes showed significantly improved power conversion efficiencies (PCEs) compared to DSSCs sensitized with N3 alone. These findings represent a significant advancement in solar cell technology, paving the way for more efficient and sustainable energy solutions.

Summary: Here, a metal-free organic dye (CCPICPB) with panchromatic absorption in the near-infrared range was synthesized. The dye's photophysical properties were studied and validated through experimental and theoretical simulation. Pristine and calcium-doped TiO2 microspheres were synthesized using a solvothermal approach. The performance of CCPICPB dye on these materials was evaluated, with the Ca-TiO2 photoanode-based device showing higher efficiency. Co-sensitization of CCPICPB dye with Ru(II) dye resulted in further efficiency improvement, attributed to improved V-OC and J(SC) due to the dye's compensatory effect and inhibition of electron recombination.

Summary: In this study, a natural dye from the flowers of Mussaenda erythrophylla was extracted separately in ethanol and de-ionized water and employed as a photosensitizer in DSSCs. The stability and adsorption of the dye on the P25-TiO2 surface were confirmed. The optical properties of the dye were studied with regard to dye concentration and pH. DSSCs fabricated with the dye extracted in ethanol showed the best power conversion efficiency due to the optimal absorption of light in the visible region.
