Molecular weight dependent vertical composition profiles of PCDTBT:PC(71)BM blends for organic photovoltaics
We have used Soxhlet solvent purification to fractionate a broad molecular weight distribution of the polycarbazole polymer PCDTBT into three lower polydispersity molecular weight fractions. Organic photovoltaic devices were made using a blend of the fullerene acceptor PC(71)BM with the molecular we...
