Systems, Methods, and Apparatus for Integrated Glass Units Having Adjustable Transmissivities

A method of changing an infrared transmissivity of a window, the method comprising:

• applying a first voltage at the adjustable window, the adjustable window including a first conducting oxide layer, a second conducting oxide layer, and a spectral tuning layer formed between the first conducting oxide layer and the second conducting oxide layer;
• and
• generating an electrical potential between the first conducting oxide layer and the second conducting oxide layer,
• wherein generating the electrical potential causes an infrared transmissivity of the spectral tuning layer to change.

A method of forming a window, the method comprising:

• forming a substrate;
• forming a first conducting oxide layer over the substrate;
• forming a spectral tuning layer over the first conducting oxide layer;
• forming an ion conductor layer over the spectral tuning layer;
• forming an ion storage layer over the ion conductor layer;
• and
• forming a second conducting oxide layer over the ion storage layer,
• the spectral tuning layer operable to change an infrared transmissivity of the window in response to an applied voltage.
