Title: Energy-harvesting chromogenic devices

Abstract

An aspect of the present disclosure is a device that includes a switchable material and an intercalating species, such that when a first condition is met, at least a portion of the intercalating species is associated with the switchable material and the switchable material is substantially transparent and substantially colorless, and when a second condition is met, at least a fraction of the portion of the intercalating species is transferred from the switchable material and the switchable material is substantially transparent and substantially colored.
