Smart windows with high visible transmission can control the absorption or transmission spectrum of solar irradiation based on seasonal variations and personal preferences, allowing buildings to save energy. However, it is a considerable challenge to design a metasurface with high solar modulation ability (ΔAsol), integral luminous transmittance (Tlum), transmission light's color rendering index (Ra) and simple structure for smart windows. In this work, we design and optimize the asymmetric-structured multilayer and micro-nano array by applying the method of scanning parameters and fully-connected network methods. The optimization results show that ΔAsol and Tlum negatively correlate when the transmitted light of these two structures has a high Ra. This conclusion of designing high-performance asymmetric-structured metasurfaces provides essential guidance for designing future smart windows.
