Abstract:
The electrochromic window is a promising technology for reducing energy consumption related to thermal comfort in glass buildings. However, the leakage of liquid electrolytes in the electrochromic window hinders the application of electrochromic windows. Solid polymer electrolytes have been synthesized to address this issue. The fibroin-based solid electrolyte has been investigated as a potential solution to address environmental concerns and reduce the reliance on petroleum-based solid electrolytes. This study investigated the effects of the electrolyte thickness (727 μm) and lithium salt concentration (7.2521.75 wt%) on ionic conductivity. Consequently, the electrochromic window's optical density and coloration efficiency were examined. Moreover, ATR-FTIR and UV-Vis spectrophotometers were used to characterize the change in the secondary structure of silk fibroin and the light transmission caused by the addition of lithium salt and varying thickness. The results showed that the highest ionic conductivity of 0.4 mS/cm, achieved in the electrolyte containing a 14.5 wt% lithium salt with a thickness of 10 ± 1 μm, was 3.3 times lower than that of the liquid electrolyte. Furthermore, the optimal electrolyte was assembled into the electrochromic window consisting of WO₃ and NiO-based electrodes. After the applied potential of -3.0 V, the transmittance of visible and NIR light decreased from 74.15% to 3.20% and from 74.22% to 3.04%, resulting in the coloration efficiency of 124.66 and 126.73 cm²/C, respectively.
