Photo-active polymers have required excellent photo absorption property and broad absorption range. To realize above, iso-indigo dye, strong electron withdrawing property, was adopted polymer main-chain using Suzuki coupling polymerization. Also, polymer containing iso-indigo dye with spacer has a band gap about 1.68 eV. As a result, polymer shows broadened absorption range and is available for near IR absorption over 700nm. The synthesized polymer was characterized by 1H-NMR, GPC, UV-vis spectroscopy and Cyclic voltammogram for structural and opto-electrical analysis and device were fabricated and characterized photovoltaic properties. |
