Christian B. Nielsen, Bob C. Schroeder, Afshin Hadipour, Barry P. Rand, Scott E. Watkins, and Iain McCulloch, London (2011)

A new benzotrithiophene-containing donor–acceptor type copolymer for polymer solar cells is reported. The promise of benzotrithiophene as a weak donor material is reflected in a polymer band gap of 1.75 eV affording a high Voc of 0.81 V and a moderate PCE of 2.2% in a polymer solar cell.
