Episode 5: Gold ion migration influences electrical behavior of perovskite devices
Episode 5
Monday, 16 March, 2026
In this podcast episode, MRS Bulletin’s Sophia Chen interviews Barry Rand and his graduate student Tuo Hu at Princeton University about their research on how perovskites interact with metals. For their device, the researchers made a sandwich of gold and indium tin oxide with the perovskite methylammonium lead triiodide in the middle. The charges in their device move two to three orders of magnitude slower than charges in a solid-state electrolyte battery, leading the researchers to draw parallels between the two types of devices. This work was published in a recent issue of Energy and Environmental Science.
