Answer 2

Answer:

I agree and think for all homogeneous materials, such as semi-conductors used in photovoltaics, you can use the Beer-Lambert-Law. For photovoltaics, where you would like to harvest the spectrally broad solar spectrum, you have to consider additionally that the absorption coefficient (alpha) typically changes with the wavelength of the photons. In particular, in silicon alpha strongly decreases with the wavelength resulting in drastically longer penetration lengths of the photons in the material.
