Enhancement of photovoltaic performance in ferrocenyl π-extended multi donor-π-acceptor (D-D'-π-A) dyes using chenodeoxycholic acid as a dye co-adsorbent for dye sensitized solar cells.

ABSTRACT: A new set of multi-donor [ferrocene (D) and methoxyphenyl (D')] conjugated D-D'-π-A based dyes [Fc-(OCH₃-Ph)C[double bond, length as m-dash]CH-CH[double bond, length as m-dash]CN-R{R[double bond, length as m-dash]COOH (1) and C₆H₄-COOH (2)}] were synthesized as sensitizers for dye-sensitized solar cell (DSSC) applications. These dyes were characterized with the aid of analytical and spectroscopic techniques such as FT-IR, HR-Mass, and ¹H and ¹³C NMR. The thermal stability of the dyes 1 and 2 were investigated using thermogravimetric analysis (TGA) and was found to be stable around 180 °C for dye 1 and 240 °C for dye 2. The electronic absorption spectra for sensitizers display major bands between 400 and 585 nm that could be ascribed to
