Abstract
Compositions for use in HIL/HTL applications include intrinsically conductive polymer, planarizing agent, and dopant, which are soluble in non-aqueous solvents. Block copolymers of regioregular alkyl/alkoxy- and aryl-substituted polythiophenes can be used. The compositions can be formed into thin films. Excellent efficiency and lifetime stability can be achieved.
