In this work, we discovered a high density of voids at the perovskite-substrate interfaces of the bladed and spun perovskite films with a variety of compositions by peeling them off from the substrates. The … · We found that dimethyl sulfoxide (DMSO), which is a liquid additive broadly applied to enhance perovskite film morphology, was trapped during film formation and led to voids at perovskite … However, most research efforts have focused on stabilizing perovskite-metal electrode interface through surface passivation (10) or post-fabrication treatment (11), whereas the imbedded perovskite … In this review, we summarize the defect properties in perovskite films and present methodologies to control the defects density, including the growth of large size crystals, photo-curing method, grain … Department of Applied Physical Sciences, University of North Carolina, Chapel Hill, NC 27599, USA.
