Two examples are \b[<poly(3-hexylthiophene)>, <P3HT>], a conjugated polymer commonly used as an electron donor, and \b[<PCBM>], a soluble fullerene derivative commonly used as an electron acceptor. Both are <organic semiconductors>; “organic” does not imply that their transport properties are identical. Their blend is a familiar donor-acceptor photovoltaic model system.
