Buildings account for about one-third of global energy consumption and emission of greenhouse gas. Besides, as the population increases, more high-rise buildings arise, leading to energy scarcity and increased greenhouse gas emissions. Hence, designing and building sustainable structures utilizing smart windows that are energy efficient and adapt to climate change is necessary. In this context, building structures incorporated with thermoelectric-based smart windows acquire energy efficiency by selectively absorbing/reflecting infrared light and transmitting visible light. Upon exposure to sunlight, the thermoelectric-based smart window becomes dynamically active. As a result, the transition in optical properties from a visibly absorbing/reflecting state to a visibly transparent state occurs to control the solar heat gain and balance the heating/cooling loads. In this context, thermochromic windows exhibit transitional optical properties to temperature changes. Fabrication of smart windows requires thermochromic materials with critical transition temperature, fast transition kinetics, a narrow hysteresis width, and high solar modulation ability. In this context, the project aims to fabricate energy-sustainable metal halide perovskite-based thermochromic windows using the spray pyrolysis technique and tune its critical transition temperature by incorporating polymers.
