“…Among the synthesized dyes, the rhodanine-3-acetic acid acceptor based dyes shows high maximum absorption wavelength (l max ) with highest molar extension coefficient (e). This is because of strong electron withdrawing ability of rhodanine-3-acetic acid acceptor [39]. In close agreement with the design strategy, the absorption spectrum of AB dye nicely combines the optical features of the individual and symmetric counterparts A, B and AA, BB, respectively.…”

A new acrylonitrile derivative, 2-(4-bromophenyl)-3-{5-[2-cyano-2-phenylethenyl]furan-2-yl}acrylonitrile (BPCPFA, 3)which is a potential material for application in organic solar cells, was synthesized by a three-step reaction. The structures of the molecules synthesized in these steps were characterized by using various spectral analyses. BPCPFA was investigated as an electron acceptor molecule in next generation organic solar cells. Theoretical prediction and experimental studies for photovoltaic performance were also performed. Based on these results, it is concluded that BPCPFA with extended conjugated system has good and promising photovoltaic performance with Voc value as 0.96 V.

“…Compound 2a was prepared according to the reported literature [33,36]. Freshly distilled POCl 3 (25 eq) was added drop wise to DMF (23 eq) under an atmosphere of N 2 at 0°C, and then it was stirred for 1 h. TPA (2 g, 8.16 mmol) was added to the above solution, and the resulting mixture was stirred for 4 h at 95°C.…”

“…However, the absorption of the dianchoring organic dye BIBA (399 nm) in the conjugation pathway is red shifted by 15 nm compared to MIBA (384 nm) dye. This is because the increase of electron acceptors in dye mol ecule is beneficial to intramolecular charge transfer [33]. Moreover, the molar extinction coefficients (ε) of BIBA (ε = 45.969 M -1 cm -1 ) is larger than MIBA (ε = 36.924 M -1 cm -1 ) dye.…”

Two new organic sensitizers of type D π A (Donor π Acceptor) and D (π A) 2 were designed and synthesized to understand the effect of anchoring mode towards TiO 2 film which leads to influence the effi ciency of the fabricated dye sensitized solar cells. These dyes were synthesized based on the triphenylamine as electron donor, phenylhydrazine as π conjugated spacer and 4 iodobenzoic acid as anchoring/acceptor group and characterized by 1 H, 13 C NMR and mass spectroscopy studies. The optical absorption of sensitiz ers shows red shift as well as high molar extinction co efficient with extension of the π conjugation and the quantum chemical calculation studies were performed to provide sufficient driving force for electron injec tion into conduction band of TiO 2 . The DSSC based on type D (π A) 2 shows power conversion efficiency (PCE = η) 1.07% under simulated AM 1.5 G; due to more positive HOMO values, higher IPCE values, high adsorption capacity on TiO 2 as well as longer electron life time of dye.
