Abstract

The manufacturing and operation of window size (30 cm by 90 cm) electrochromic devices is described. Both the electrochromic electrode (WO₃) and the counter electrode (V₂O₅) were deposited by sol-gel method. Electrochromic measurements were performed on both electrodes and the complete device to correlate device performance to fabrication conditions. The paper describes the affects of temperature on the switching characteristics of electrochromic window. The devices were tested in the temperature range between 10 degrees Celsius and 50 degrees Celsius. The switching algorithm described in this paper ensures identical optical performance of electrochromic device in the wide range of temperatures. The algorithm is based on the charge control and does not require monitoring of device transmittance.
