摘要

Solution-processed organic solar cells (OSCs) have attracted considerable attention due to their unique advantages like flexibility, semitransparency, and fabrication of large-area modules via low-cost roll-to-roll processing [1].The core of an OSC is the bulk-heterojunction photoactive layer, which consists of electron donors and electron acceptors.The leading electron donors are ptype conjugated polymers, and the electron acceptors are typically n-type conjugated small molecules [2].This kind of OSCs is alsoknown as polymer solar cells (PSCs).
