Abstract

original image

A systematic evaluation of a novel conjugated polymer, bearing alkyl side chains on both the donor and acceptor units, is conducted using nanoscale characterization techniques and device fabrication. How to manage the use of solvent additives to achieve power-conversion efficiencies of up to 3.7% is demonstrated.
