Abstract:
1. An apparatus for applying electrical potential to an electrochromic device and configured to electrochromically switch the electrochromic device where the electrochromic device comprises a first electrode comprising a cathodically coloring conducting polymeric material, a second electrode comprising an anodically coloring conducting polymeric material, and an electrolyte disposed between and in electrochemical communication with the first and second electrode, the apparatus comprising: a. a photosensor configured to receive light and convert such light to a photosensor potential; and b. a controller in electrical communication with the photosensor and the electrochromic device, the controller configured to deliver a continuous voltage that is pulsed to the electrochromic device in response to the photosensor potential, the continuous voltage sufficient to electrochromically switch the electrochromic device; wherein the cathodically coloring conducting polymeric material comprises a substituted or unsubstituted 2,2-dibenzyl-3,4-propylenedioxythiophene monomer.
