Recently, as the fossil fuels strongly decreased, several studies have been conducted in order to exploit solar power as an alternative source of energy. To make this possible with sustainable costs, the attention has been focused on the development of organic photovoltaic solar cells (OPVs) based on polymeric photoactive layer. The aim of this work is to describe the synthesis and characterization of new copolymers, poly[3-(6-fullerenylhexyl)thiophene-co-3-(6-bromohexyl)thiophene], starting from soluble regioregular (PT6BrR) and regiorandom (PT6Br) homopolymeric precursors. These materials are new intrinsically conductive copolymers made of thiophenic units bearing a fullerene and a bromine atom at the end of a hexylic side chain. The obtained homopolymers and copolymers have been widely characterized with different techniques, such as 1H-NMR, FT-IR and UV-Vis spectroscopy, thermal analysis (DSC and TGA) and gel permeation chromatography (GPC). All the synthesized materials were tested as active media in organic solar devices of BHJ type, blended with PC61BM (1:1 w/w) as the acceptor material and as double-cable materials.
