دستگاه الکتروکرومیک – کامسول

Electrochromic devices (ECDs) may be employed in ”smart” windows, for instance in buildings or motor cycle visors, where the transparency of the device can be controlled by applying a voltage.

ECDs make use of the fact that the absorbance of visual light for a chemical species in a solution may depend on the oxidation state.

By the use of electrodes to control the oxidation state, the transparency of the whole cell can be controlled by changing the potential.

This model simulates the dynamical change of the transparency of an en electrochemical cell when subject to a potential step, followed by relaxation either at open circuit or by short circuiting the cell.
