1 Introduction. Polymer solar cells (PSCs) have gained much attention as renewable photovoltaic technology because of their transparency, light weight, and low-cost solution processing compatible with roll-to-roll manufacturing.
Controlling and optimizing the photoactive layer morphology is closely related to the process of exciton dissociation, charge transfer and collection and thus is crucial for building a high-performance polymer solar cell (PSC). Due to the limited solubility of non-halogenated solvents and the strong crystall
