Title: Energy-harvesting chromogenic devices

Abstract

The present disclosure relates to devices that include a perovskite, where, when a first condition is met, at least a portion of the perovskite is in a first phase that substantially transmits light, when a second condition is met, at least a portion of the perovskite is in a second phase that substantially absorbs light, and the perovskite is reversibly switchable between the first phase and the second phase by reversibly switching between the first condition and the second condition.
