Abstract
A non-fullerene acceptor polymer includes a structure represented by formula (I). Formula (I) is defined as in the specification. The non-fullerene acceptor polymer has an electron donating unit and an electron attracting end group. The non-fullerene acceptor polymer uses phenyl or its derivatives as the linker to form the polymer.
