TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The electrically conductive particles are metallic particles, which are silver flakes (preferred), gold, palladium and/or nickel. The metallic particles are present at 70-90%, preferably 80%. In the photovoltaic device, the layers include a layer of: amorphous or crystalline silicon; copper indium gallium (di)selenade; or aluminum and a layer of a crystalline silicon material. The transparent conducting oxide is indium tin oxide. In the layered assemblies, the electrically conductive member exhibits a contact resistivity of less than 20 ohm.cm2.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: (A) further comprises a reactive diluent and a free radical initiator. Preferred Components: The reactive diluent is hexane diol diacrylate and is present at 1-10%, preferably 4-7%. The free radical initiator: is 2,5-dimethyl-2,5-di(t-butylperoxy)-3-hexyne and/or dicumyl peroxide; and is present at 0.01-2%, preferably 0.3%.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: (A) further comprises an epoxy triacrylate oligomer. Preferred Components: (a) and/or (b) are each present at 0.1-30%. The epoxy triacrylate oligomer is aliphatic and is present at 0.1-25%. The thin layer has a thickness of 1-100 microns, preferably 15-70 microns. Preferred Method: (A) is applied to a thickness of 10-70 microns, preferably 15-50 microns. The step of heating is carried out at 200 degrees C for 5 seconds to 20 minutes. EXAMPLE - 2,5-Dimethyl-2,5-di(t-butylperoxy)-3-hexyne (0.3 wt.%) was mixed with hexane diol diacrylate (4 wt.%). Then a trifunctional aliphatic epoxy acrylate (7.85 wt.%) and a modified epoxy acrylate resin (7.85 wt.%) were added to the mixture to obtain a precursor composition. The precursor composition was mixed thoroughly until a homogenous resin mixture was obtained. Then silver flakes (80 wt.%) were added to the precursor composition to produce an electrically conductive and thermally curable composition.
