تحضير فلم من البولي الأنيلين المعزز بأكسيد الغرافين المرجع واستخدامه كإلكترود مضاد في الخلايا الشمسية الصباغية

Abstract

Hybrid film of Polyaniline (PANI) and the reduced Graphene oxide (rGO) has been deposited on transparent conductive substrates (ITO) via new chemical method. The (PANI/rGO) and Polyaniline films were characterized by the (FTIR) spectroscopy and (UV-Vis) spectrophotometry. The electrochemical properties of the (PANI/rGO) film was studied via cyclic voltammetry (CV) where the conductivity increased approximately seven times compared to the

initial value of PANI film. The surface morphology was examined by scanning electron microscopy )FE-SEM). The (PANI/rGO) film was used as a counter electrode in the dye-sensitized solar cell which prepared using shami- berries and ZnO nanofilm. the film morphology was examined using atomic force microscopy. The nanoparticles size obtained was of the order of 50 nm and the band gap energy was about 3.26 eV. The photo conversion efficiency of the dye-sensitized solar cell was about 2.65% with fill factor of 0.9.
