Claims7
An electrochromic device comprising a low-temperature solution processed metal oxide, the low-temperature solution processed metal oxide comprising a titanium oxide, and wherein the low-temperature solution processed metal oxide:
- is disposed adjacent to an electrolyte layer and an electrochromic layer;
- and
- is disposed at a cathode of the electrochromic device and releases charges to an anode that includes an electrochromic polymer;
- wherein the electrochromic polymer:
- is switched, through the release of charges from the low-temperature solution processed metal oxide, between a fully bleached state and a fully colored state;
- and
- has a transmissivity, in the fully bleached state, of between about 15% and about 60% within a visible spectrum, within which wavelengths range from between about 380 nm to about 700 nm.

An electrochromic device comprising:
- a charge storage material including a titanium oxide, the charge storage material being disposed at a cathode of the electrochromic device;
- and
- an anode including an electrochromic polymer;
- the electrochromic polymer being switched, through an application of charges by the charge storage material, between a fully bleached state and a fully colored state, the electrochromic polymer in the fully bleached state having a transmissivity of between about 15% and about 60% within a visible spectrum, within which wavelengths range from about 380 nm to about 700 nm.
