Design of Metal Wires-based Organic Photovoltaic Cells

An organic photovoltaic architecture based on conducting polymer and organic compounds deposited concentrically on long metal wires were introduced and designed. The light enters to photovoltaic cells through a semitransparent outer electrode. Preliminary tests on the potential to realize the model in conventional flat devices was carried out. Insertion of a hole collecting layer, poly (ethylene dioxythiophene) doped with polystyrene sulfonic acid (PEDOT:PSS), to between the active layer and the outer electrode, and increasing in the wettability of PEDOT:PSS solutions on polymer-thin films were found to increase in power conversion efficiencies of photovoltaic cells. The power conversion efficiency of 0.11% was obtained from the devices tested, which is reasonably high enough for further development in metal wires-based organic photovoltaic cells.
