A copolymer composition comprised of alternating donor and acceptor monomers has been developed for potential application in polymer-based organic photovoltaic cells, or use as conducting or light-emitting materials in microelectronic devices. Organic solar cells are attracting attention as potential cost-effective alternatives to silicon-based solar cells. These alternative photovoltaic devices require tunable, conductive polymers with low band gaps that enable harvesting of a larger fraction of the solar spectrum.   
•  Tunable band gap
•  Demonstrated power conversion when applied in photovoltaic devices
