Terahertz Microscopy Imaging Reveals How to Boost Perovskite Performance

To better evaluate perovskite solar cell material(s), scientists at the U.S. Department of Energy’s Ames National Laboratory developed a microscope that simultaneously images at the terahertz (THz) frequency and nanometer spatial scales. Through THz nanoimaging, the scientists uncovered unexpected information about methylammonium lead iodide (MAPbI3) perovskite that could improve the material’s solar cell performance.
