Absorption coefficient of silicon
Wavelength dependent absorption coefficient of c-silicon at 295K with uncertainty. Also contains the temperature coefficient for transferring the data to other temperatures.
Information on these data can be found in: C. Schinke et al., Uncertainty analysis for the coefficient of band-to-band absorption of crystalline silicon, AIP Advances 5, 067168 (2015)
Refractive index of silicon
Wavelength dependent refractive indices and extinction coefficients of silicon and typical solar cell coatings and glazing used in photovoltaics. Also includes data on reflectivity of solar cell backsheets.
