摘要

Over the past three years,n-type organic semiconductor (n-OS) electron acceptors with an acceptor-donor-acceptor (A-D-A) structure and a ladder-type conjugated fused ring donor core have been extensively explored for the application in polymer solar cells (PSCs),because of their excellent optical absorption properties and flexible energy level variability [1].
