Spectral splitting optimization for efficient hybrid solar energy cell is studied by materials which are Na3AlF6, Y2O3, and TiO2. The Essential Macleod software is used to design this beamsplitter. Multilayer coating design consist of Na3AlF6 as low index material, Y2O3 as middle index material and TiO2 as high index material. The wavelength range of design is from 400nm to 2000nm with reference wavelength 700nm having incident angle 45 degree. Design consists of 56 alternating layers based on formula [LMHM]^14. Optimac refinement techniques is used to improve the design. It is concluded in the result that a good beam splitter is designed which transmits about 80% light in the spectrum range from 400nm to 975nm and reflect 77% light in the infrared region from 1000nm to 2000nm. The transmitted light is used for the solar cell and reflected light is used for thermoelectric generator.
