Green‐Processed Non‐Fullerene Organic Solar Cells Based on Y‐Series Acceptors
The development of environmentally friendly and sustainable processes for the production of high‐performance organic solar cells (OSCs) has become a critical research area. Currently, Y‐series electron acceptors are widely used in high‐performance OSCs, achieving power conversion efficiencies above 19%. However, these acceptors have large fused conjugated backbones that are well‐soluble in halogenated solvents, such as chloroform and chlorobenzene, but have poor solubility in non‐halogenated green solvents. To overcome this challenge, recent studies have focused on developing green‐processed OSCs that use non‐chlorinated and non‐aromatic solvents to dissolve bulk‐heterojunction photoactive layers based on Y‐series electron acceptors, enabling environmentally friendly fabrication. In this comprehensive review, an overview of recent progress in green‐processed OSCs based on Y‐series acceptors is provided, covering the determination of Hansen solubility parameters, the use of non‐chlorinated solvents, and the dispersion of conjugated nanoparticles in water/alcohol. It is hoped that the timely review will inspire researchers to develop new ideas and approaches in this important field, ultimately leading to the practical application of OSCs.
