Abstract

© 2014 AIP Publishing LLC. High performance electrochromic devices have been fabricated and demonstrated utilizing a solid polymer electrolyte and zinc oxide (ZnO) nanowire (NW) array counter electrode. The poly(methyl methacrylate) based polymer electrolyte was spin coated upon hydrothermally grown ZnO NW array counter electrodes, while electron beam evaporated NiOx thin films formed the working electrodes. Excellent optical contrast and switching speeds were observed in the fabricated devices with active areas of 2cm2, exhibiting an optical contrast of 73.11% at the wavelength of 470nm, combined with a fast switching time of 0.2 s and 0.4 s for bleaching and coloration, respectively.
