NOVELTY - A layer configuration on a support (A), comprises a non-photoactive element exclusive of poly(3,4-alkylenedioxythiophene) and poly (3, 4-dialkoxythiophene). The non-photoactive element contains a first polymer containing structural units of formula (I), and a second polymer different from the first polymer.    USE - For use in electronic device such as light emitting diode, photovoltaic device, transistor, and electroluminescent device (claimed), solar cells, batteries, capacitors, smart windows, electrochromic devices, and sensors for organic and bio-organic materials.    ADVANTAGE - The configuration provides an element between a positive electrode and a material capable of hole transport capable of reducing hole-electron recombination at the positive electrode, thus increasing the efficiency and lifetime of electronic devices containing such layer configuration.    DETAILED DESCRIPTION - A layer configuration on a support, comprises a non-photoactive element exclusive of poly(3,4-alkylenedioxythiophene) and poly (3, 4-dialkoxythiophene). The non-photoactive element contains a first polymer containing structural units of formula (I), and a second polymer different from the first polymer and is from quaternized polyamine-polymers, polysulfo-polymers, polyphosphoric acids and polyphosphoric acid salts. The surface of one side of the element is contiguous with a positive electrode and the surface on the opposite side of the element is contiguous with a material capable of transporting holes.
