Refractive index of amorphous silicon

WebJan 13, 2024 · Hydrogenated amorphous silicon (a-Si:H) is known for exhibiting light-induced metastable properties that are reversible upon annealing. While these are commonly associated with the well-known deleterious Staebler–Wronski effect in the field of thin-film silicon solar cells, the associated changes in optical properties have not been well studied. WebThe refractive index of silicon was measured at room temperature over the range 1.1–2.0 μ by autocollimation in an ~12° wedge. The image was observed by sweeping it across a slit in front of a lead sulfide cell whose output was displayed vertically on an oscilloscope while the sweep frequency was displayed horizontally. The problems of measuring the …
