NOVELTY - The quensor sheet (11) for electric energy storage or retrieval comprises conducting films, an axis normal to the surfaces, a donor, an acceptor, a linker, a gap, a pair, and a composite polymer. The pair comprises the donor and the acceptor chemically bonded to the linker. A tunneling gap is provided between adjacent donor and acceptor.    USE - The invention is used for electric energy, e.g. solar electric energy, storage or retrieval.    ADVANTAGE - The invention is low cost and eliminates pollution by substituting for gasoline in automotive vehicles.    DETAILED DESCRIPTION - The quensor sheet for electric energy storage or retrieval comprises first and second surfaces, first and second conducting films on the surfaces, an axis normal to the surfaces, a donor, an acceptor, a linker, a gap, a pair, and a composite polymer. The pair comprises the donor and the acceptor chemically bonded to opposite ends of the linker. Pairs are located head to tail on the axis, with 5-30 Angstrom gap between each adjacent pair. The conducting films are metal films (12, 13). The composite polymer comprises first and second polymer chains (4, 4'), OXYZ axes. The surfaces on the sheet are parallel to the YOZ plane. The composite polymer film is stretch-oriented parallel to the OZ axis. The first and second metal films are on the surfaces of the sheet. The donor and acceptor are chemically bound to the first polymer chain. The second polymer chain is an insulator. The first and second polymers are in the weight proportion (1-x) and x respectively, where (x/(1-x)) is lesser than 3 but greater than 20. A tunneling gap is provided between adjacent donor and acceptor chemically bound to the first polymer chain, a first strip electrode, and a second strip electrode. The first strip electrode is connected on one edge of the film to the first conducting film, and the second strip electrode is connected on the other edge to the second conducting film.
