In this paper we present measurements of the photovoltaic response of bulk donor-acceptor heterojunction between the conjugated polymer, 3m speedglas 9002nc poly(3-octylthiophene), P3OT, (as a donor, D) and fullerene (methanofullerene), (as acceptor, A), deposited between indium tin oxide and aluminum electrodes.The innovation involves the substrate, which is a polymer foil instead of glass.These devices are based on ultrafast, reversible, metastable photoinduced electron transfer and charge separation.We also present the efficiency and stability studies on large area (6 cm x 6 cm) flexible plastic anodized pearl price xbox solar cells with monochromatic energy conversion efficiency (e) of about 1.
5% and copyright collection efficiency of nearly 20%.Further more, we have investigated the surface network morphology of these films layers by atomic force microscope (AFM).The development of solar cells based on composites of organic conjugated semi-conducting polymers with fullerene derivatives can provide a new method in the exploitation of solar energy.
