At Room Temperature The Absorption Coefficient A In A Sihx Assume Ks 13 2 Is About 104 Cm2 At 1 6 Ev And 105 Cm At 1 (219.97 KiB) Viewed 14 times

At room temperature, the absorption coefficient a in a-SiHx (assume ks = 13.2) is about 104 cm2 at 1.6 eV and 105 cm--at 2.0 eV. If coated with materials with refractive index of n = 3.0 at 2.0 eV and the matrial that provide the maximum transmittance at 1.6 eV. Compare the required thickness to capture 80 % of the photons at these energies.
