摘要

A new series of low-bandgap alternating polyfluorenes with different donor-acceptor-donor moieties have been synthesized. Electrochemical and optical absorption measurement show that onset bandgaps of these polymers range from 1.2 to 1.5 eV. These polymers, blended with a C_(70)-derivative as acceptor, are used for solar cell fabrication. Devices show promising photovoltaic properties, and the spectral response of photocurrent covers all visible and near-infrared wavelength regions with its onset extended to 1 μm. The best data gives a photocurrent density of 3.4 mA/cm~2, open circuit voltage of 0.58 Vand power conversion efficiency of 0.7% under illumination of AM1.5 (1000 W/m~2) from a solar simulator.
