title: Morphology Evolution in High-Performance Polymer Solar Cells Processed from Nonhalogenated Solvent.
abstract: A new processing protocol based on non-halogenated solvent and additiveis developed to produce polymer solar cells with power conversion efficiencies better than those processed from commonly used halogenated solvent-additive pair. Morphology studies show that good performance correlates with a finely distributed nanomorphology with a well-defined polymer fibril network structure, which leads to balanced charge transport in device operation.
