Optical absorption at 10.6 μm in silicon is mainly due to lattice absorption and free carrier absorption. Amorphous silicon or hydrogenated a-Si:H is an important material for photovoltaic devices. These devices consist of films with thicknesses of about 1 ,um and it is important to know the refractive index and absorption coefficient as function of wavelength to predict the photoelectric behaviour of a device. 2013-03-02 · The absorption coefficient of single-crystal silicon is very important for applications in semiconductor processing and solar cells. However, large discrepancies exist in the literature about the absorption coefficient of silicon, especially in the visible and near-infrared region.

However, large discrepancies exist in the literature about the absorption coefficient of silicon, especially in the visible and near-infrared region. The absorption coefficient, α, is related to the extinction coefficient, k, by the following formula: $$\alpha=\frac{4 \pi k}{\lambda}$$ where λ is the wavelength. If λ is in nm, multiply by 10 7 to get the absorption coefficient in the units of cm-1. Additional optical properties of silicon are given in the page Optical Properties of Silicon.

Doping concentration are given in the text. This leads to a typical optical absorption coefficient below 0.1 cm −1 at room temperature which was confirmed experimentally.
