Externet Posted April 28, 2018 Share Posted April 28, 2018 Sunlight after a prism, with several equal solar cells placed to receive each of the colors individually... Which color produces more energy ? Should depend on the spectral response/sensitivity of the cells; but is there a color yielding more energy ? Ultraviolet ?

It also depends on the spectrum of the sun and on the selective transmissivity of the atmosphere. UV has a higher energy per photon than visible wavelengths, but a lower Intensity, because the sun emits less of it and the atmosphere blocks a large part of it. Here you can see the result. The largest intensity is in the visible range, which is no coincidence, since we evolved to be most receptive to the most common wavelengths.
