A solid-state electrochromic device is disclosed comprising tungsten oxide-Prussian blue complementary configuration in combination with a proton-conducting polymer electrolyte. A novel proton-conducting copolymer, especially useful in transparent electrochromic cells, comprising the reaction product of a vinyl sulfate monomer with a comonomer selected to form an alternating copolymer, such as vinylpyrrolidone, is disclosed. Novel transparent complementary electrode materials for electrochromic cells are disclosed, of the general formula [M1]4[M2(CN)6]3 wherein M1 may be indium, gallium, gadolinium, lanthanum, and M2 is iron. Unlike Prussian blue (where M1 and M2 are both iron), the complementary electrode materials of the present invention are stable, and do not have to be precharged. An electrochromic transparency comprising an electrochromic film and an ion-conductive layer disposed between a pair of electrodes is disclosed wherein the optical properties and electrochromic efficiency are improved by means of a metal grid electrode, wherein adhesion of the metal grid to an acidic polymer electrolyte is improved by means of a primer coating comprising a copolymer of acrylamidopropane sulfonic acid and acrylic acid.
