1. An electrochromic structure, comprising:
a first transparent non-conductive (GLASS-I) layer;
a first transparent conductor (CONDUCTOR-I) layer coupled to the GLASS-I layer;
an ion storage layer coupled to the CONDUCTOR-I layer;
an electrolyte layer coupled to the ion storage layer;
an electrochromic layer coupled to the electrolyte layer;
a second transparent conductor (CONDUCTOR-II) layer coupled to the electrochromic layer; and
a second transparent non-conductive (GLASS-II) layer coupled to the CONDUCTOR-II layer,
wherein the electrochromic layer includes perovskite nickelates thin films formed on the CONDUCTOR-II layer and which has crystalline grains of the size of about 5 nm to about 200 nm resulting in intergranular porosity of about 5% to about 25%.
