The aim of this project is to achieve and charaterize a completely solid electrochrome device, with modular transmission, on a sno#2 conductive glass substrate, composed by two complementary electrochromic materials, Polyaniline has anodic staining and tungsten oxide has cathodic staining, separated by a protonic electrolyte polymer.; Le but de cette these vise a la realisation et a la caracterisation d'un dispositif electrochrome entierement solide, a transmission modulable, sur substrat de verre conducteur sno#2, compose par deux materiaux electrochromes complementaires, la polyaniline a coloration anodique et l'oxyde de tungstene a coloration cathodique, separes par un electrolyte polymere protonique.
