Episode Synopsis "ECE 695NS Student Presentation: Optimization and Analysis of Multilayer Anti-Reflection Coating for Thin-Film Si Selective Solar Absorber"

To increase the absorption of the thin film selective solar absorber, multilayer anti-reflection coating is designed and optimized, which consists a layer of SiO2 followed by TiO2. Local optimization is performed for 20 um Si and at 550C. The optimal thicknesses for SiO2 and TiO2 are found to be 100nm and 50nm respectively, which yields 76.59% thermal transfer efficiency at 100 suns concentration. ...
