Abstract: Solar cell fabriation using thiophene based synthesized copolymer were done with an inverted configuration. Sythesized copolymer, PEFL obtained in powdered form was deposited as thin film after preparing its solution by dissolving in chlorobenzene. Spin coating technique was chosen for casting thin films. Band gap of PEFL thin film was determine by taking optical absorption spectrum and were found to be ∼ 2.16 eV. Photovoltaic devices were fabricated with device structure ITO/ZnO/PEFL:PCBM/Ag. This device exhibited a high open circuit voltage of 1.05 V. [ABSTRACT FROM AUTHOR]
