Polyacetylene thin film photovoltaic devices
2014 Photovoltaic devices have been obtained by a direct polymerization of undoped (or p-type doped) thin film (CH)x layer onto a polycrystalline cadmium sulfide film. The morphology of the contact is observed by S.E.M. microscopy. The electrical characteristics of this device are studied in the dark or under illumination. The main result, at AM1, 100 mW/cm2 with doped (CH)x correspond to 0.5 p...
متن کاملCharacterization of Polyacetylene and Polyacetylene Doped with Palladium
Samples of Naarmann polyacetylene, denoted as N-(CH)x, (unstretched) and polyacetylene doped with Pd have been investigated, being characterized by: (i) conductivity using the four-point method, (ii) bulk concentration of Pd using the atomic absorption method, (iii) bulk density using helium pycnometry, (iv) surface composition by X-ray photoelectron spectroscopy and (v) electron transport para...
متن کاملPolyacetylene glycosides from Gymnaster koraiensis.
Two polyacetylene glycosides, gymnasterkoreasides A and B, were isolated from the roots of Gymnaster koraiensis. Their structures were elucidated to be (3R)-8-decene-4,6-diyne-1,3-diol 1-O-beta-D-glucopyraside and (3R)-8-decene-4,6-diyne-1,3-diol 1-O-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyraside on the basis of spectroscopic analysis including COSY, HMQC, and HMBC experiments, as well as ch...
متن کاملPolyacetylene: Myth and Reality
Polyacetylene, the simplest and oldest of potentially conducting polymers, has never been made in a form that permits rigorous determination of its structure. Trans polyacetylene in its fully extended form will have a potential energy surface with two equivalent minima. It has been assumed that this results in bond length alternation. It is, rather, very likely that the zero-point energy is abo...
متن کاملMass transfer analysis for unsteady thin film flow over stretched heated plate
In this paper, the mass transfer in a time varying thin liquid film over a stretching heated plate having variable temperature and concentration is analyzed. The analytical solution for the unsteady NavierStokes, energy and diffusion equations are obtained. A new similarity is found using group-theoretic analysis which renders the exact similar governing equations amenable to analytical solutio...
