Halide perovskites show ubiquitous presences in growing fields at both fundamental and applied levels. Discovery, investigation, and application of innovative perovskites are heavily dependent on the synthetic methodology in terms of time-/yield-/effort-/energy- efficiency. Conventional wet chemistry method provides the easiness for growing thin film samples but represents as an inefficient way for bulk crystal synthesis. A team of researchers in the US (Pennsylvania State University, U.S. Army CCDCAMC) has developed a universal solid state-based route for synthesizing high-quality perovskites by means of simultaneously applying both electric and mechanical stress fields during the synthesis, i.e., the electrical and mechanical field-assisted sintering technique. They employed various perovskite compositions and arbitrary geometric designs for demonstration and established a synthetic route with uniqueness of ultrahigh yield, fast processing and solvent-free nature, along with bulk products of exceptional quality approaching to single crystals. According to the researchers their process to fabricate large perovskite devices is more cost- and time-effective than previously possible and it may accelerate future materials discovery… read more.
