If memory serves me well, photovoltaic cells produce more energy per Watt illumination with blue light than with red because blue photons are more energetic whereas photoconductive cells have a minimum energy threshold and will conduct current based on the Watts/sq. meter in any wavelength above the threshold.

By the way, I said coloUr sensitive, not "color"
