In this article we doped Black phosphorus quantum dots (BPQD) in the light absorption layer of the hybrid perovskite solar cells (HPSCs), which enhanced the photon conversion efficiency (PCE) of the solar cell from about 11.8% to 12.4% and open voltage from 0.9V to 0.95V. After we do more detailed investigations by SEM and Photoluminescence (PL), we find that this enhancement is caused by BPQD introducing the growth of larger size grain of perovskite crystals and broaden band gap of Perovskite with BPQD and better carrier transport property of perovskite with BPQDs.
