%X Performance of solar control filter depends strongly on the individual layer thicknesses as well as the quality of their interfaces. In this work, a numerical modeling was designed and implemented to optimize the layer thicknesses of Cu2O/CuS, Cu2O/Cu and CuS/Cu thin films for use as solar control filter using transfer matrix. The result shows that for Cu2O/CuS, with CuS in contact with the substrate, the optimized layer thickness of 110/30nm and for CuS/Cu and Cu2O/Cu with Cu in contact with the substrate, the optimized layer thickness are 110/30nm and 100/30nm, respectively. The model also predicted transmittances of 67% for Cu2O/CuS, 42% for CuS/Cu and 64.5% for Cu2O/Cu at 550nm. A transmittances of 24.9-36.9% of IR radiation for all the films was realized. These results, when compared with previous works indicate the possibility of improvement in the performance of the filters.
