Spectral Splitting Optimization for Highly Efficient Hybrid Photovoltaic Devices by Using Na3AlF6, Y2O3 and TiO2 Beam Splitter
Abstract:
This research study utilises Essential Macleod software to optimize beam splitter for efficient hybrid photovoltaic application. The spectral splitting was carried out by alternating multilayer coating designs having Na3AlF6 as low index material, Y2O3 as middle index material and TiO2 as high index material. The wavelength range of optimized design was selected from 400 nm to 1000 nm with reference wavelength 510 nm at an incident angle of 45. The beam splitter model comprises 56 alternating layers based on the formula [LMHM]14. The Optimac refinement approach is used to enhance the modelled structure. Different built-in analysis techniques in the essential Macleod package are also used to analyze our design, like density, total absorptance and admittance diagram. It is concluded that the modelled beam splitter transmits about 90% light in the visible spectrum range and reflects 90% light in the infrared region, which is very useful for an application like solar cells and the thermoelectric generator.
