We have been developing organic semiconducting materials which constitute the active layer of an organic thin-film solar cell. Our primary focus is on producing electron-donor materials. In order to establish a guiding principle of donor materials for higher conversion efficiency, we have investigated various main-chain structures of donor polymers, basing on the quinoxaline-based donor polymer (N-P7) which have been developed by us and shows power conversion efficiency over 5%. This year, we have synthesized and characterized a variety of narrow band-gap polymers in which conjugated alternating blocks are composed of various electron-rich and electron-deficient moieties. Among these materials, Polymer-1 in a solid state showed narrow band-gap of 1.58 eV and a high absorption coefficient of approximately 200,000 cm-1 together with a high field-effect transistor hole mobility of 1.0E-02 cm2/Vs. Organic solar cell properties of Polymer-1 were investigated using 70PCBM as an electron acceptor in bulk heterojunction (BHJ) type devices with a structure of anti-reflection film / glass substrate / ITO / PEDOT:PSS / donor:acceptor / cathode buffer layer / metal cathode. The photovoltaic device having approximately 300 nm thick BHJ active layer showed a 10.6 % (Jsc = 21.7 mA/cm2, Voc = 0.762 V, FF = 0.641) of power conversion efficiency under an illumination of AM 1.5 G at 100 mW/cm2.
