However, the random mixing of donors and acceptors in the BHJ often suffers the severe charge recombination in the interface, resulting in poor charge extraction. Herein, we propose a new approachtreating the surface of the zinc oxide (ZnO) as an electron transport layer with potassium hydroxideto induce vertical phase separation of an active layer incorporating the nonfullerene acceptor IT4F.
