ABSTRACT:
A method of preparing an efficient photoresponsive device includes the steps of providing a first electrode on a substrate, providing a layer of an organic material including a blend of at least two semiconductive polymers having different electrode affinities and/or different ionization potentials over the first electrode, providing a second electrode over the layer of organic material, at least one of the electrodes being a transparent or semi-transparent, to form a photoresponsive device, and thermally annealing the photoresponsive device.
