Solar absorptance of zincalume
WebThe absorptance (blue) is directly measured using a photoaccoustic spectroscopy technique and an absorption peak of 22% is observed at λ∼6 μm. For comparison, the absorptance of a uniform tungsten film at this wavelength range is ∼1%. Therefore, a more than 20 times absorptance enhancement is achieved at the photonic band edge of λ∼6 μm.
