Abstract
Photoelectrochromic cells fabricated with titanium photo-electrode prepared by screen printing, tungsten trioxide electrochromic electrode prepared by electrodeposition and laminated by a Polyvinyl butyral polymer based ion conductor are introduced in this study. The fabricated processes save lots of equipment cost compare to sputter process. Polyvinyl butyral quasi-solid electrolytes reduce the solvent leakage, volatilities and provide excellent optical and physical properties such as high transmittance, elasticity and impact-resistance. The visible transmittance of the quasi-solid PEC device is varied between 50% (bleached state) and 16% (coloured state). On the other hand, the solar radiation transmittance is varied between between 52% and 7%. After 60 days, the PEC device maintain 72% visible transmittance range and 85% solar radiation transmittance range, respectively. In falling ball impact testing, the interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the steel ball completely pierce the glass.
