Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to calculate the lifetime mobility product μτ for a project. In order to do this I need to calculate the photogeneration. Therefore I need the light intensity and absorption coefficients. I understand how to calculate light intensity, and I have come up with an experiment to try. I do not fully understand what an absorption coefficient is, or how to find/estimate it.

If anyone understands this principle, please let me know. I am not looking for a solution necessarily, but just a general understanding of absorption coefficients or photogeneration would be greatly appreciated.

Thanks!
