Abstract

The aim is to investigate the influence of a buffer layer on the performance of polymer solar cells with ITO/buffer layer/MEH-PPV:C60/Al structure where indium tin oxide (ITO) was used as anode, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) as donor, fullerene molecule (C60) as acceptor and aluminium (Al) as cathode. At first step, polyaniline (PANI) was prepared by an aqueous oxidative polymerization reaction. In the next step, the synthesis PANI was used as buffer layer in polymer solar cells and results were compared with fabricated device by using PEDOT:PSS. The fabricated device with polyaniline (PANI) demonstrated a significant increment in the short circuit current density ( Jsc) ,open circuit voltage (Voc ) and fill factor (FF), as compared to fabricated device with PEDOT:PSS.
