MONOLITHIC MULTI-LAYER ELECTROCHROMIC COMPOSITE MATERIAL WITH INNER BUFFER LAYERS

摘要

An EC composite material (10) is capable of transmitting light and is usable in an ECD that has an optical substrate and conductor structure connected to a power supply (16). The EC composite material is positionable on the optical substrate and connectable to the power supply via the conductor structure. Power input results in the composite material changing from substantially colorless transparent condition to a substantially colored transparent condition. The EC composite material includes plural outer layers, a central EC layers, a central EL layer with a top and bottom surface, and a central IS layer. There is also a buffer layer material that improves bidirectionnal charge transfer between the electrochromic layer and the ion-storage layer. The composite material also includes a supply of mobile ions, a contact structure (12) connected to the layers and connectable to such conductor structure to allow such power-input.
