Fig. 6From: Effects of Process Parameters on the Characteristics of Mixed-Halide Perovskite Solar Cells Fabricated by One-Step and Two-Step Sequential CoatingThe XRD patterns of perovskites, deposited by spin-dip (run 1), spin-spin (run 10), and one-step (run 11) methods. The asterisk denotes the perovskite peaks, the number sign denotes the FTO peaks, and the plus sign denotes the PbI2 peaksBack to article page
