%0 Journal Article %J Solar Energy Materials and Solar Cells %D 2008 %T Self-consistent optical parameters of intrinsic silicon at 300 K including temperature coefficients %A Martin A Green %K Absorption coefficient %K optical properties %K SILICON SOLAR CELLS %X An updated tabulation is presented of the optical properties of intrinsic silicon, of particular interest in solar cell calculations. Improved values of absorption coefficient, refractive index and extinction coefficient at {300&\#xa0;K} are tabulated over the 0.25–1.45&\#xa0;μm wavelength range at 0.01&\#xa0;μm intervals. The self-consistent tabulation was derived from {Kramers–Kronig} analysis of updated reflectance data deduced from the literature. The inclusion of normalised temperature coefficients allows extrapolation over a wide temperature range, with accuracy similar to that of available experimental data demonstrated over the {−24&\#xa0;°C} to {200&\#xa0;°C} range. %B Solar Energy Materials and Solar Cells %V 92 %P 1305–1310 %G eng %U http://www.sciencedirect.com/science/article/pii/S0927024808002158 %R 10.1016/j.solmat.2008.06.009
