High-Efficiency Metamorphic Multijunction (HEMM) Concentrator Solar Cell: The HEMM solar cell is a triple-junction device—a solar cell with three layers—that uses "mismatched" materials. It is the first solar cell to break the 40% conversion efficiency barrier—the solar equivalent of breaking the four-minute mile

high-efficiency(>14%) and air-stable carbon-based, all

Mar 26, 2021 · The inferior crystallinity and phase stability of CsPbI2Br films have severely hindered the development of carbon-based, all-inorganic perovskite solar cells (PSCs). Herein, we demonstrate the preparation of CsPbI2Br films by the top-seeded solution growth (TSSG) technique. It is performed through spin-coating of CH3NH3Br (MABr) atop CsPbI2Br precursor film prior to annealing, during …
