Herein, we report four metal-free organic polymethacrylates (In-In-BzI)PMA, (Ac-In-BzI)PMA, (TPA-In-BzI)PMA, and (Py-In-BzI)PMA with pendant chromophores donor-pconjugated-acceptor (D-p-A) molecular framework as photosensitizers for dye-sensitized solar cells (DSSCs). In which the donor-acceptor units are attached by an indole-chalcone extending side chain to inhibit back electron transfer and charge recombination; the p-linker component contains varied chalcone-based substituents to enhance the sunlightharvesting ability of the solar device. Photon-current cells based on the DSSC format were fabricated using the polymers as sensitizers. The DSSC device assembled using (TPA-In-BzI)PMA exhibits a considerably better IPCE peak and J-V response, with an overall power conversion efficiency of 3.70% under the illumination of AM 1.5G (100 mW cm -2 ).
