Claims20
An electrochromic device comprising:
- a charge storage layer comprising a metal bronze, an electrolyte layer, and an electrochromic layer disposed between two transparent electrodes,
- wherein the charge storage layer is solution processed and formed at a temperature no greater than about 150° C.,
- the charge storage layer is amorphous and/or a hydrate, and
- the charge storage layer exhibits a visible-range transmittance of at least about seventy percent at a film thickness between about twenty nanometers and about two hundred nanometers.
1 more element
A method of making a charge storage layer for an electrochromic device, comprising:
- forming a solution comprising a metal bronze by contacting molybdenum with hydrogen peroxide in an alcohol solvent at about ambient temperature;
- coating the solution onto a substrate to form a wet layer;
- and
- drying the wet layer at a temperature no greater than about 150° C. to form a solid film that is amorphous and/or a hydrate,
- wherein the solid film exhibits a visible-range transmittance of at least about seventy percent at a film thickness between about twenty nanometers and about two hundred nanometers.
