Abstract：

The　weak　donor-strong　acceptor　polymer　acceptors　for　all-polymer　solar　cells　(all-PSCs)　have　gained　much　less　attention　compared　with　the　typical　donor-strong　acceptor　counterparts.　Direct　(hetero)arylation　polymerization　reaction　is　a　rising　synthetic　method,　although　most　of　the　naphthalene　diimide　polymer　photovoltaic　acceptors　have　been　prepared　by　classic　Stille　polymerization.　A　weak　donor-strong　acceptor　polymer　acceptor　PNB2F　has　been　successfully　designed　and　synthesized　by　the　two-step　direct　(hetero)arylation　reaction　and　further　applied　in　all-PSCs.　The　all-PSC　device　based　on　PNB2F　and　electron-donating　polymer　PBDB-T　gained　a　PCE　of　4.49%.　The　results　demonstrate　that　direct　(hetero)arylation　reaction　is　a　promising　tool　for　building　efficient　polymer　acceptors　with　convenient　and　low-cost　synthesis　ideas.
