Application Number: 636067
Filing Date: 12/08/2006
Publication Date: 05/03/2007
A -donor(D)-bridge(B)-acceptor(A)-bridge(B)- or derivative type block copolymer system used in a tandem device of multiple sub-cells, where donor (D) is an organic conjugated donor (p-type) block, acceptor (A) is an organic conjugated acceptor (n-type) block, and bridge (B) is a non-conjugated and flexible chain, has been designed and preliminarily tested for potential lightweight, flexible shape, cost-effective and high efficiency "plastic" thin film solar cell or photo detector applications. A `tertiary supramolecular nanophase separated structure` derived from this -DBAB- block copolymer is expected to improve opto-electronic (photovoltaic) power conversion efficiency significantly in comparison to all existing reported organic or polymeric donor/acceptor binary photovoltaic systems due to the reduction of "exciton loss," the "carrier loss," as well as the "photon loss" via three-dimensional space (morphology) and energy level optimizations. The tandem stacking of block copolymer sub-cells further enables optical excitation energy gap grading to improve photon capture of solar spectrum and device efficiency.

United States Patent 20070014916
Organic and inorganic light active devices and methods for making the same
Inventors: Daniels, John James (Higganum, CT, US)
Application Number: 453627
Filing Date: 06/14/2006
Publication Date: 01/18/2007
A light active device includes a semiconductor particulate dispersed within a carrier material. A first contact layer is provided so on application of an electric field charge carriers having a polarity are injected into the semiconductor particulate through the carrier material. A second contact layer is provided so on application of the electric field to the second contact layer charge carriers having an opposite polarity are injected into the semiconductor particulate through the carrier material. The semiconductor particulate comprises at least one of an organic and an inorganic semiconductor. The semiconductor particulate may comprise an organic light active particulate. When constructed as a light emitting device, an electric field applied to the semiconductor particulate through the carrier causes charge carriers of opposite polarity to be injected into the semiconductor particulate. The charge carriers combine to form carrier pairs which decay and give off light.
