Prof. Edwin TSO’s group published a review paper entitled “Perovskite Smart Windows: The Light Manipulator in Energy-Efficient Buildings” in Advanced Materials (IF 29.4).

Uncontrolled sunlight entering through windows contributes to substantial heating and cooling demands in buildings, which leads to high energy consumption from the buildings. Recently, perovskite smart windows have emerged as innovative energy-saving technologies, offering the potential to adaptively control indoor solar heat gain through their impressive sunlight modulation capabilities. Moreover, harnessing the high-efficiency photovoltaic properties of perovskite materials, these windows have the potential to generate power, thereby realizing more advanced windows with combined light modulation and energy harvesting capabilities.

This article provides a comprehensive review of perovskite smart windows, encompassing the material fundamentals and characteristics of chromic perovskites, device-level development and application of perovskite smart windows with light-modulating and/or light-harvesting functions, and building-level performance evaluation and demonstration for thermal management and energy-saving. This review aims to facilitate the advancement of perovskite smart window technologies.
