TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The inorganic oxides comprise (mg/kg) titanium oxide (5-20, preferably 10), cerium oxide (2-15, preferably 7), calcium (50-200, preferably 80), potassium (2-15, preferably 10) and iron (2-15, preferably 10). The amount of fullerene or carbon nanotubes in third layer is 10-80% by weight based on the total weight of P3OT. The semiconductors, elements and/or inorganic oxides are dispersed in aromatic substituted solvent. The aromatic substituted solvent is dichlorobenzene. The second layer is film of an electrically conductive material with electropositive potential of 4-6 (preferably 4.5-5.5) eV, to facilitate collection of positive electric charges. The base material of second layer is polythiophene, polyethylene dioxythiophene/polystyrene sulfonate (PEDOT/PSS), colloidal gold, conductive oxides and/or chromium-oxygen compounds. The acrylic and/or methacrylic matrix is acrylic and/or methacrylic esters e.g. 2-propenol acid, (1-methyl-1,2 ethanediyl)bisoxy(methyl-1,2-ethanediyl)ester, 2-propenoic acid, 2-methyl-1,2-ethanediylbis(oxy-2,1-ethanediyl)ester, 2-propionic acid, 2-(hydroxymethyl)-2-((1-oxo-2-propenyl)oxy)methyl-1,3-propanediyl ester, 2-propenoic acid, 1,1'-(2.2-bis((1-oxo-2-propen-1-yl)oxy)methyl propanediyl)ester. The acrylic or methacrylic matrix comprises sensitive initiators comprising benzyl dimethyl ketal (DMPA), benzoin ethers (SME), hydroxyl alkyl phenyl ketones (HAP), dialkoxy acetophenones (DEAP). The heat-sensitive initiators are diacyl peroxides, dibenzoyl peroxide, dilauryl peroxide or azobisisobutyronitrile (AIBN). The electrode layer has thickness of 2-10 (preferably 5) mu m. The active layer has thickness of 1-20 (preferably 5) mu m. The counterelectrode layer comprises material with electronegative potential of 2.5-5 (3-4.5) eV, to facilitate collection of negative electric charges. The counterelectrode layer is optically transparent and comprising gold, silver, aluminum, colloidal calcium, conductive polymers e.g. polythiophene, polyethylene dioxythiophene/polystyrene sulfonate (PWOT/PSS). The counterelectrode layer has thickness of 2-50 (preferably 5) mu m, to ensure optical transparency. The at least one protective layer comprises optically transparent and electronically inert material, deposited on successive underlying layers to protect and encapsulate, and forming single hermetically sealed unit. The base material of protective layer is insulating and transparent oxides silicon dioxide, epoxy resins, vinyl polymers, e.g. polymethyl methacrylate and/or polymeric encapsulating agents. The multilayer photovoltaic composition optionally comprises auxiliary layer for absorbing moisture and gas in the underlying layers, and to be interposed between fourth counterelectrode layer and protective layer. The absorbing layer comprises zeolites either dispersed in liquid carriers, or incorporated in or associated with fifth layer to be in contact with gases and vapor of the underlying layers. The base materials of successively deposited layers are in a liquid or pasty state during the deposition process.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polyethylene dioxythiophene/polystyrene sulfonate (PEDOT/PSS) has density and viscosity modified by mechanical or chemical removal of its aqueous component and is possibly added with thickening materials. The polyethylene dioxythiophene/polystyrene sulfonate (PEDOT/PSS) is dispersed in acrylic or methacrylic matrix, suitably filled with additives having light or heat sensitizing properties, to increase polymerization capacity and speed. The PPV derivatives are poly(2-methoxy-5-(2'-ethylhexoxy)-1,4-phenylenevinylene) (MEH-PPV) and poly(2-methoxy-5-(3,7-dimethyloctoxy)-p-phenylenevinylene) (OC1C10-PPV).
