Abstract

A carbazole based new n-type conjugated polymer (CP) has been synthesized and employed as a photosensitizer in polymer-sensitized solar cells (PSSCs). The synthesis of CP was accomplished by the reaction of appropriate monomer dialdehyde with aromatic dinitriles, under Knoevenagel condensation conditions followed by its characterization by ¹H NMR and FT-IR. The band gap of CP measured by cyclic voltammetry (CV), density functional theory (DFT) and diffuse reflectance (DR) UV-vis spectroscopy revealed closely matched values of 2.57, 2.47, and 2.64 eV respectively. Under the illumination of AM1.5G (100 mW cm⁻²), CP based PSSCs exhibited power conversion efficiency of 2.08% with a short-circuit current density (J_SC) of 7.0 mA/cm², an open-circuit voltage (V_oc) of 534 mV and a fill factor (FF) of 55.85%.
