Vapor Fix Boosts Up Perovskite Crystal Performance

Researchers from King Abdullah University of Science and Technology have developed a simplistic and mild bromine treatment that eliminates surface and bulk defects from perovskites and boosts the materials’ optoelectronic properties. In this approach, bromine vapors enter the surface of as-synthesized perovskite crystals to reach their deep-lying layers, eliminating surface and bulk deficiencies formed during crystal development. Researchers were astounded to know that bromine vapors overpowered metallic lead on the surface as well as in the bulk of the crystals. This eventually allowed them to access the bulk features of these crystals, such as their electrical conductivity.
