Perovskite Photovoltaic Smart Window: A Low-Cost Solution for Net-Zero Electricity Generation.
This project aims to develop a low-cost smart window using thermochromic perovskite solar cells (PSCs), which can switch between transparent and tinted semi-transparent states based on the surrounding environment. The smart windows will serve two main purposes: (i) generating electricity and powering a building in the semi-transparent state, and (ii) allowing sufficient visible light to enter the building in the transparent state.
Utilising thermochromic PSCs, the smart windows will provide additional electric power while reducing the amount of heat entering buildings, ultimately decreasing energy consumption from air conditioners and enabling net-zero electricity generation. This innovative technology has the potential to revolutionise sustainable building design by providing an efficient way to generate clean energy while enhancing the visual comfort of indoor spaces.
The project will focus on scaling up production and commercialising the technology.
