Organic solar cells (OSCs) have emerged as one of the highly promising avenues in renewable energy due to their lightweight, flexible nature and the potential for low-cost manufacturing. This review provides a comprehensive overview about OSCs processed by halogen-free solvents. First, the state-of-the-art donor and acceptor materials are elaborated, and the design principles for efficient molecules are summarized. Second, the strategies for developing high-performance OSCs processed using nonhalogen solvents are investigated, including solvent engineering for solution pretreatment, thermal processing, and layer-by-layer techniques. Finally, prospects for future research directions are provided, highlighting the need for continuous innovation in nonhalogen solvent-processed OSCs, breaking through existing constraints, and driving the advancement of OSC technologies into the future.
