Lead-free double perovskite Cs2AgBiBr6 has attracted much attention due to its environmental stability and low toxicity, which has bee used in photovoltaic devices. Unfortunately, the power conversion efficiency (PCE) is relatively low owing to poor-quality film. In this paper, CuBr2 was added in the precursor to improve the crystalline of the perovskite film. Maybe Cu2+ was reduced to Cu + by DMSO, so Cu + existed in the Cs2(Ag1-xCux)BiBr6 perovskite films. The carbon electrode-based and hole-free solar cells with the planar structure of FTO/c-TiO2/Cs2(Ag1-xCux)BiBr6/C were fabricated. The ef...
