a Transmittance spectra of the pristine thermochromic perovskite window (TPW) and MTPW, together with the AM1.5 G solar spectrum. b Photographs of the TPW and MTPW comparing their optical haze. c Optical haze of the TPW, perhydropolysilazane-coated thermochromic perovskite window (PTPW) and MTPW in the wavelength range of 300–800 nm. d 1, 3 and 5 are the surface scanning electron microscopy (SEM) images of the pristine TPW, PTPW and MTPW, respectively, while 2, 4 and 6 are the 3D optical surface profiles and roughness of the pristine TPW, PTPW and MTPW, respectively. e Light propagation through a rough surface.
