Abstract
The Optical multilayer perovskite thin films were integrated as a basic structure with smart window systems for Green buildings to to develop energy outputs, and the structure was numerically simulated due to its strong light–matter interaction and tunable optical and physical properties. We propose the Transfer Matrix Method (TMM), which was implemented in MATLAB. We used fixed constants and selected variables in order to study the differences. The variable was represented by the addition of a TiO₂ layer to the structure under study. First, we studied structure without TiO₂. After that, we studied the multilayer structure where we used three thicknesses for TiO₂ (20, 50, and 100 nm) For each case, we analysed important optical properties such as spectral stability, solar energy regulation, rejections of unwanted reflection, and transmission behaviour. The study was carried out in the visible spectral range. We calculated absorbance, reflectance, and transmittance for each case. From all of the above, we observed the enhanced performance of perovskite thin films highlighted their effectiveness in optical energy management. This can help thin-film researchers in the field of optics and photonics to design multilayer structures that can confine light efficiently through rapid, scalable, and optimizable modelling processes.
