Morphological Degradation in Low Bandgap Polymer Solar Cells – An In Operando Study

Abstract

The morphology and the photovoltaic characteristics of a polymer–fullerene bulk-heterojunction solar cell processed with a processing additive are probed simultaneously. The processing additive reversibly enhances the solar cell performance which decays when the additive is lost.
