Vapor fix lifts up solar cell performance

A facile and mild bromine treatment eliminates surface and bulk defects from perovskites to boost the materials’ optoelectronic properties.


​A simple and noninvasive treatment could become a prime post-crystallization process to optimize the optoelectronic properties of hybrid perovskite solar cell materials.

In this treatment devised by KAUST, bromine vapors penetrate the surface of as-synthesized perovskite crystals to reach their deep-lying layers, removing surface and bulk defects generated during crystal growth.
