In this letter, solution-processed black phosphorus quantum dots (BPQDs) were applied to enhance hole extraction of Si/poly-(3, 4-ethylenedioxythiophene): poly (styrenesulfonic acid) (PEDOT:PSS) heterojunction based hybrid solar cells. A remarkable improvement of power conversion efficiency (PCE) from 10.03% to 13.60% was achieved by the PEDOT: PSS/BPQDs-incorporated devices. Detailed investigations discover the influence of BPQDs on the hole extraction effect and work mechanism of BPQDs. Our work presents an avenue in using solution processed BPQDs for high performance hybrid solar cells. (C) 2018 Elsevier B.V. All rights reserved.
