Abstract

We report the fabrication of a complementary electrochromic device (CECD) in the form of glass/indium-tinoxide (ITO)/NiO/gel-polymer electrode (GPE)/MoO³/ITO/glass, and the integration of a CECD/GaAs-based triple-junction (TJ) solar cell system. It was found that the maximum transmittance in the bleached state was 68.05% at 580 nm. With a solar radiation intensity of 100 mW/cm², it was found that an optical contrast in transmittance at 580 nm could reach 58.73%. It was also found that the coloration time and bleaching time of the integration CECD/TJ solar cell system were 6 and 15 s, respectively.
