This document discusses hybrid photo- and electrochromic materials that can be used for energy conservation. It introduces Neil Branda of Switch Materials Inc. and describes how these materials can change between light and dark states when activated by light or electricity. This allows them to be used in applications like variable transmission windows for buildings and vehicles, where they can reduce energy losses by controlling the penetration of light and heat. The materials consist of a gel electrolyte film encapsulated between transparent glass sheets and electrodes, with a hybrid layer that switches between transparent and dark states.
