  • Patent number: 8241522
    Abstract: The invention provides liquid crystalline blends, a device such as a photovoltaic cell using the blend and method thereof. A liquid crystalline blend comprises at least an electron donor and at least an electron acceptor with a weight or molar ratio in the range of from about 1:20 to about 20:1. Another liquid crystalline blend comprises at least an electron donor and at least an electron acceptor, wherein the electron donor, the electron acceptor, or both is (are) halo-substituted such as F-substituted. The donor or the electron acceptor can be excited by an electromagnetic radiation such as solar light to induce electron transfer between the donor and the acceptor. The photovoltaic cell is improved in that favorable molecular arrangement in the blend gives more interfaces between the donor and the acceptor and thus a viable path for dissociation and electrons and/or holes; as well as larger light-harvesting area toward the coming light.
