A nonfullerene acceptor for wide band gap polymer based organic solar cells.
نویسندگان
چکیده
A new 1,8-naphthalimide based planar small molecular acceptor and two benzothiadiazole based wide band gap (WBG) polymer donors P1 and P2 were synthesized for nonfullerene organic photovoltaic cells (OPVs). Devices based on fluorinated polymer P2 achieved a highly improved PCE of 3.71% with an open circuit voltage (V(oc)) of 1.07 V, which is beyond the currently known levels for nonfullerene OPVs with the V(oc) higher than 1 V.

In this research, a new phenanthroline derivative was synthesized and characterized on purpose to polymerize the monomer via a Stille-polymerization with different electron donating moieties leading to a range of new wide band gap polymers. The novelty in this monomer would be the long side chains in order to ensure the solubility of the entire polymer. Hence there would be no necessity for the...
