Polish National Science Centre grant no 2015/17/D/ST5/01343 “Synthesis and characterization of novel conjugated polymers for non-fullerene heterojunctions with enhanced separation of photogenerated charge carriers”
In this project we undertake the issue of polymer architecture appropriate for the bulk heterojunction with improved photoexcited charge separation and high electron mobility. We propose a new concept of macromolecules with general structure of polymers the connection of conjugated donor-acceptor main chain D-π-A 1 with non-fullerene acceptor A 2 connected through flexible linker. This concept is an attempt to solve the main issues of non-fullerene organic photovoltaics (OPVs) based on bulk heterojunction (BHJ).
