Dual band electrochromic windows enable selective spectral control of the incoming solar radiation in buildings and can therefore efficiently respond to their ever-changing lighting, heating and cooling requirements. They allow indeed to selectively filter out near-infrared solar radiation passing through the window, thus blocking solar heat gain during hot summer days and increasing it over sunny winter days, whilst regulating the amount of daylight in an independent manner. We herein present advancements in the manufacturing and the performance of screen-printed dual-band electrochromic devices (herein referred as “plasmochromic”) embodying stable gel electrolytes. Particularly three different sets of polymeric hosts, respectively based on PMMA/PEO-, PVB- and PVDF, are characterized for such integration. Most suitable formulations have been adopted to manufacture and test up to 30 x 30 cm²-large smart window prototypes. Based on the values of T_LUM, T_SOL, and total solar heat gain coefficient (g-value) calculated from the measured transmittance and reflectance spectra, a preliminary assessment of the device optical and thermal performances for architectural integration in insulated glazing units is carried out, compared with the performances of competing commercially available solar control and smart glazing IGU. The results demonstrate the potential of the proposed “plasmochromic” technology in reducing the energy consumption and maximizing both visual and thermal comfort in architectural glazing systems.

双波段电致变色窗户能够对建筑物中入射的太阳辐射进行选择性光谱控制，因此可以有效地响应其日新月异的照明，采暖和制冷要求。它们确实允许选择性地过滤掉穿过窗户的近红外太阳辐射，从而在炎热的夏季阻止太阳热量的吸收，并在阳光明媚的冬日增加太阳的热量，同时以独立的方式调节日光的数量。我们在此提出了体现稳定的凝胶电解质的丝网印刷双波段电致变色器件（在本文中称为“等离子致变色”）的制造和性能方面的进步。特别地，表征了分别基于PMMA / PEO-，PVB-和PVDF的三组不同的聚合物主体以进行这种整合。^2-大的智能窗口原型。根据T _LUM，T _SOL的值以及根据测得的透射率和反射光谱计算出的总太阳热增益系数（g值），对隔热玻璃中用于建筑集成的设备光学和热性能进行了初步评估。与竞争的商用太阳能控制和智能玻璃IGU的性能相比。结果证明了拟议的“等离子变色”技术在减少能耗以及最大程度地提高建筑玻璃系统的视觉和热舒适性方面的潜力。
