Synergistic effect of solvent and solid additives on morphology optimization of organic solar cells

Suzhou, China (SPX) Nov 08, 2021 Controlling the morphology of photoactive layers towards nanoscale bi-continuous donor/acceptor interpenetrating networks is a key issue to build high-performance organic solar cells (OSCs). Due to the distinct properties between donor and acceptor materials, casting an active layer from a single solvent solution usually results in an either insufficient or excessive phase separation that
