4,4′‐Biphenol (BPO), a common, cheap chemical, is employed as a “molecular lock” in blends of fluorine‐containing polymer or small molecule donors and fullerene acceptors to lock donors via hydrogen bond formed between the donor and BPO. The molecular lock is a versatile key to enhance the efficiency and stability of organic solar cells simultaneously.
