The synthesis of novel conjugated polymers, designed for the purpose of photovoltaic energy conversion, and their properties in polymer/fullerene materials and photovoltaic devices are reviewed. Two families of main chain polymer donors, based on fluorene or phenylene and donor-acceptor-donor comonomers in alternating copolymers, are used to absorb the high-energy parts of the solar spectrum and to give high photovoltages in combinations with fullerene acceptors in devices. These materials are used in alternative photovoltaic device geometries with enhanced light incoupling to collect larger photocurrents or to enable tandem devices and enhance photovoltage.

Nyckelord: heterojunction solar-cells, open-circuit voltage, photocurrent spectral, response, low-bandgap polyfluorene, conjugated polymers, quantum, efficiency, gap polyfluorene, charge-transport, acceptor units, trapping light
