Design of Metal Wires-based Organic Photovoltaic Cells

9th Eco-Energy and Materials Science and Engineering Symposium, EMSES 2011 ; 25 May 2011 through 27 May 2011 ; Chiang RaiAn 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
