Single-Crystal Perovskites Made with Standard Practices Are Stable, Flexible
LA JOLLA, Calif., Aug. 6, 2020 — Engineers at the University of California, San Diego have developed a way to fabricate perovskites as single-crystal thin films. The method, which uses standard semiconductor fabrication processes including lithography, produces flexible, single-crystal perovskite films with controlled area, thickness, and composition. According to the researchers, these single-crystal films show fewer defects and are more efficient and stable than polycrystalline perovskites. The new fabrication method could
