Abstract:
1. A method for forming an electrochromic device, comprising: (a) forming a first conductive electrochromic layer; (b) forming a first solid ion conductor layer having a thickness between about 1 nm and 300 nm over the first conductive layer, wherein the first solid ion conductor layer is formed using a deposition technique selected from the group consisting of sputtering, evaporation, CVD, PECVD, ALD, pulsed laser deposition, plating, and sol-gel; (c) forming a second solid ion conductor layer having a thickness between about 1 nm and 300 nm on the first solid ion conductor layer, wherein the second solid ion conductor layer is formed from a different material than the first solid ion conductor layer, wherein the second solid ion conductor layer is formed using a deposition technique selected from the group consisting of sputtering, evaporation, CVD, PECVD, ALD, pulsed laser deposition, plating, and sol-gel, and no buffer layer is formed between the first solid ion conductor layer and the second solid ion conductor layer; and (d) forming a second conductive counter electrode layer over the second solid ion conductor layer.
