The electronic structure and reflectivity of PEDOT:PSS from density functional theory

The geometric and electronic structure of condensed phase organic conducting polymer PEDOT:PSS blends has been investigated by periodic density functional theory (DFT) calculations with a generalized-gradient approximation (GGA) functional, and a plane wave basis set. The influence of the degree of doping of the PEDOT polymer on structural and optical parameters such as the reflectivity, absorbance, conductivity, dielectric function, refractive index and the energy-loss function is studied. A flip from the benzoid to the quinoid structure is observed in the calculations when the neutral PEDOT is doped by negatively charged PSS. Also the optical properties are affected by the doping. In particular, the reflectivity was found to be very sensitive to the degree of doping, where higher doping implies higher reflectivity. The reflectivity is highly anisotropic, with the dominant contribution stemming from the direction parallel to the PEDOT polymer chain.

“…From a comparison of Figs. 5 and 11, the capacitance of the aluminum capacitor with solid electrolyte (6 of the weight ratio between iron(III) p-toluenesulfonate hexahydrate-6 H 2 O and 3,4-ethylenedioxythiophene) for the CNTs treated with acid was higher than that of the aluminum capacitor with liquid electrolyte at the beginning of potential cycling since the conductivity (100 S cm ¹1 ) of solid electrolyte (PEDOT) is higher than that (0.01 S cm ¹1 ) of liquid electrolyte 14 and the long-term operational stability for the aluminum capacitor with solid electrolyte was obviously better than that for the aluminum capacitor with liquid electrolyte. This picture may be attributed to the CNTs dispersing into the liquid electrolyte after cycling, as evidenced by the liquid electrolyte changing from light yellow to light black for the aluminum capacitor with liquid electrolyte.…”

Carbon nanotubes (CNTs) which are directly grown on nanoporous alumina templates by chemical vapor deposition are modified by acid-treatment or/and annealing and then a negative electrode is obtained. Next, alumina is deposited onto the nanoporous alumina templates with the grown as well as modified CNTs by a chemical liquid phase deposition method and then a positive electrode is obtained. Finally, the negative electrode coated with solid electrolyte polymerized by changing weight ratios between iron(III) p-toluenesulfonate hexahydrate-6 H 2 O and 3,4-ethylenedioxythiophene is assembled with the positive electrode into an aluminum capacitor. The capacitance of the aluminum capacitor reaches a maximum at 6 of the weight ratio between iron(III) p-toluenesulfonate hexahydrate-6 H 2 O and 3,4-ethylenedioxythiophene. Furthermore, the highest capacitance as well as operation potential of the aluminum capacitor and the lowest leakage current density of the aluminum capacitor at the 10000th cycle of potential cycling are obtained by the CNTs being treated with acid and annealed. Moreover, the decreasing rates of the capacitance as well as operation potential of the aluminum capacitor and the increasing rate of the leakage current density of the aluminum capacitor for the raw CNTs are quicker than those for the CNTs treated with acid or/and annealed.

Organic solar cells, both in the hybrid dye sensitized technology and in the full organic polymeric technology, are a promising alternative that could supply solar electricity at a cost much lower than other more conventional inorganic photovoltaic technologies. This paper presents a life cycle analysis of the laboratory production of a typical bulk heterojunction organic solar cell and compares this result with those obtained for the industrial production of other photovoltaic technologies. Also a detailed material inventory from raw materials to final photovoltaic module is presented, allowing us to identify potential bottlenecks in a future supply chain for a large industrial output. Even at this initial stage of laboratory production, the energy payback time and CO 2 emission factor for the organic photovoltaic technology is of the same order of other inorganic photovoltaic technologies, demonstrating that there is plenty of room for improvement if the fabrication procedure is optimized and scaled up to an industrial process.
