Herein, we report the synthesis of organic–inorganic hybrids of polyaniline‐rGO‐ZnO (PRZ) ternary composite materials for a potential application in dye‐sensitized solar cell (DSSC). A facile all‐electrochemical method was adopted for the deposition of PRZ films on FTO‐coated glass substrate. The PRZ hybrid assembly was subsequently characterized by X‐ray diffraction, Raman spectroscopy, scanning electron microscopy (SEM), cyclic voltammetry, and photoelectrochemical measurements. Further, the morphological and elemental composition features of PRZ were monitored by field emission SEM and EDX, respectively. Electrochemical impedance spectra suggest that the charge–transfer resistance for the ternary composite is distinctly decreased. The maximum conversion efficiency of DSSC with PRZ counter electrode reaches 2.84%, which is higher than that of polyaniline‐reduced graphene oxide (rGO) counter electrode. This ternary composite (PRZ) with organic–inorganic hybrid architecture showing an enhanced photoelectrochemical activity might be exploited in future as a promising material for application in next‐generation solar devices.

The article presents the conducted study to analyze the effect of chromophore substituents on the optical and redox properties of the synthesized light emitting poly(p-phenylenevinylene) (PPV)-based conjugated-nonconjugated copolymers (CNCPs). PPVs are organic conjugated polymers that could be used as materials for light emitting diodes. Among the methods used in the study are the thin-layer chromatography, Fourier transform infrared (FTIR) spectroscopy, and gel permeation chromatography (GPC).
