Abstract
Ion blocking layers are interposed between the outer electrodes and the active layers in a five-layer electrochromic device. The ion-blocking layers are optically transparent and electronically conductive to provide for electron transport while blocking the transport of ions between the active layers and the outer electrode layers.
