Organic solar cells (OSCs) have great potential to completely change the development trend of entire industries and become the next generation of commercial solar cells. Compared with polymer solar cells, the nonfullerene all‐small‐molecule organic solar cells (NF‐ASM OSCs) system has the advantages of easy purification, no batch effect, etc. Moreover, their power conversion efficiency (PCE) exceeds the commercialization threshold of 10%. Recently, the diversity of small‐molecule materials and the steady increase in PCE values suggest a bright future for NF‐ASM OSCs. Herein, small‐molecule donor and acceptor materials that have been developed in recent years to produce higher device efficiency are introduced.
