The ability to achieve energy saving in architectures and optimal solar energy utilisation affects the sustainable development of the human race. Traditional smart windows and solar cells cannot be combined into one device for energy saving and electricity generation. A VO2 film can respond to the environmental temperature to intelligently regulate infrared transmittance while maintaining visible transparency, and can be applied as a thermochromic smart window. Herein, we report for the first time a novel VO2-based smart window that partially utilises light scattering to solar cells around the glass panel for electricity generation. This smart window combines energy-saving and generation in one device, and offers potential to intelligently regulate and utilise solar radiation in an efficient manner.
在建筑中实现节能以及优化太阳能利用的能力影响着人类的可持续发展。传统的智能窗户和太阳能电池无法整合到一个设备中以实现节能和发电。二氧化钒（VO₂）薄膜能够响应环境温度，在保持可见光透明度的同时智能调节红外透过率，可作为热致变色智能窗户应用。在此，我们首次报道了一种新型的基于VO₂的智能窗户，它将部分光散射到玻璃面板周围的太阳能电池上用于发电。这种智能窗户将节能和发电功能整合在一个设备中，并具有以高效方式智能调节和利用太阳辐射的潜力。
