PHYSICOCHEMICAL AND MORPHOLOGICAL PROPERTIES OF NOVEL COPOLYMERS FOR APPLICATION IN PHOTOVOLTAIC ENERGY

Abstract

We present in this work, the synthesis and characterization of a novel copolymer from bithiophene and methylfuran, the properties of the copolymer layers were studied by electrochemical method (cyclic voltammetry), UV–vis spectroscopy and photocurrent measurements, scanning electron microscopy (SEM), conductivity measurement and photocurrent measurement techniques. The cyclic voltammogram showed one redox couple characteristic of the oxidation and reduction states of the produced copolymer. The copolymer covering the surfaces was confirmed by the scanning electron microscopy and the energy dispersive X-ray analysis. The morphological analysis of the film surfaces showed showed spherical structures formed by agglomerated particles. The photocurrent measurement shows good photoelectrochemical properties of this copolymer makes it ideal candidates for photovoltaic cells applications
