Abstract
In this study, we have synthesized conjugated n-type perylene tetracarboxylic diimide-based copolymer with 5,5′-bis(4-aminophenyl)-2- 2′-bifuryl segment (PTCDI-PFDA) as an active material for the fabrication of bulk heterojunction photovoltaic device of type ITO/PEDOT:PSS/rr-P3HT:PTCDI- PFDA/Al. The synthesized n-type copolymer (an oligomer with a relatively low molecular weight) was characterized by 1H NMR, gel permeation chromatography and thermo gravimetric analysis. The electronic and structural properties of the copolymer were investigated by UV-vis and fluorescence spectroscopy. The copolymer exhibited an optical band gap of about 1.59 eV. The HOMO and LUMO energy levels were calculate..
