We report on the selective detection of UV-A region by using a single layer of a conjugated copolymer forming a Schottky junction in connection with Al cathode. The structure of the prepared UV detector is ITO/PEDOT:PSS/poly[9,90-dioctyl-fluorene-2,7-diyl]-copoly[diphenyl-p-tolyl-amine-4,40-diyl] (B...
