Abstract

The open circuit voltage of a block copolymer (BCP) based polymer solar cell is shown to be directly influenced by the surface morphology at the metal interface. The authors clearly correlate the open circuit voltage with the amount of acceptor component at the film surface. Furthermore, they report an additional open circuit voltage rise when applying a buffer layer (PBI) instead of altering the morphology underneath.
