Paper Abstract

This paper describes the fundamental properties of the transmissive electrochromic device. The device comprises of a semi-solid electrolyte and a WO3 film sandwiched by a pair of electroconductive sheet glasses. The transmittance of the device can be arbitrarily controlled within the range from 80% to 10%. The response time was found to be greatly dependent on the size of device and the applied DC voltage. The life time for the repetitive operations is more than 105 cycles. The devices have fairly good durability against the outdoor conditions. Based on the kinetic study on tungsten bronze and the analysis of equivalent circuit, the effects of the rate determining factors are discussed.
