The objective of this proposal is to demonstrate the feasibility of producing optical filters on solar cell glass covers that will reflect multiple spectral notches that are in-band to the solar spectrum between 400 nm to 2500 nm while maintaining high throughput elsewhere for solar cell utilization.
Benefit: Fills Air Force need for coatings with spectral notches on solar cell panel cover glass. Provides stress control for very thick optical coatings enabling optical filters with unprecented performance over current filters which are limited in thickness due to stress in the coating.
