Abstract
The power conversion efficiency of PTB7:PC71BM polymer solar cells was improved to 9.1% by treatment with methanol followed by a water- and alcohol-soluble conjugated polyelectrolyte cathode interface layer. This improvement in efficiency is a result of a combination of an enriched PC71BM ratio on the top surface in the active layer and the presence of the preferred dipole at the cathode interface.
