# I Spectral Sensitivity and Solar Energy

I'm trying to understand the link between Spectral Sensitivity and Solar Energy.

To give some context, I've been learning about external quantum efficiency and spectral response.

I found a lot of literature about spectral sensitivity, with one saying the units of it were Ampres / lux.
Is spectral sensitivity a measure of the amount of current generated by the solar cell per lumen/m2?

How come it is not Ampres / radiant flux or intensity? A bit of a photometry/radiometry question I guess...
