Patterning of Metal Halide Perovskite Thin Films and Functional Layers for Optoelectronic Applications

Highlights This review discusses the status and perspectives of nano- to micron-scale patterning method for the optical management of perovskite optoelectronic devices. We provide an overview of nanopatterning/texturing technologies for perovskites to achieve a high device performance and categorize them into top-down and bottom-up approaches.
