　　Recently,various non-fullerene acceptors have been synthesis and applied to fabricate PSCs,[1-3] and PCEs of the PSCs based on non-fullerene acceptor(NF-PSCs)have been rapidly improved to the level of fullerene-based PSCs.In this work,a new combination of a conjugated polymer(PBDB-T)and small molecular acceptor(ITIC)was selected as the active layer to fabricate the devices,and a record efficiency of 11.3%was achieved.Meanwhile,the NF-PSCs with 1.00 cm2 area was fabricated and certificated,and a rated efficiency of 10.78%was achieved.
