Title Alternating copolymers of fluorene and donor-acceptor-donor segments designed for miscibility in bulk heterojunction photovoltaics Article in journal Authors Desta Gedefaw, Yi Zhou, Stefan Hellstrom, Lars Lindgren, L.Mattias Andersson, Fengling Zhang, Wendimagegn Mammo, Olle Inganäs, Mats R Andersson Publication Year 2009 Source JOURNAL OF MATERIALS CHEMISTRY, 2009, (19)30, 5359-5363 Link to Source (DOI) 10.1039/b823137k Abstract <p>A novel copolymer based on alternating fluorene and donor-acceptor-donor segments is reported, together with its photovoltaic properties in blends with fullerene derivatives. The balanced electron and hole mobility of the blends leads to a power-conversion efficiency of 2-3% under solar illumination.</p> |
