Solar Absorber Can Handle the Heat

Apr-06-17 A low-cost solar absorber able to withstand high temperatures could pave the way to concentrated solar power plants able to run twenty-four hours a day.

The technology, from a team at Purdue University, involves modifying commercially available silicon wafers with a thin film coating of tantalum and silicon nitride. This coating improves the wafer’s ability to selectively absorb photons within a specific wavelength while rejecting others, withstanding temperatures up to 535 degrees Celsius.
