This paper $[1]$ gives the following statement:

On Earth, the low-entropy energy is provided by solar radiation and the high-entropy energy is disposed as infrared radiation emitted into the cold space.

So, what suppose to mean "low-entropy energy"?

In a black body radiation, entropy of a photon gas is proportional to the cube of its temperature (see e.g. Wikipedia), which is itself an increasing function of frequency (or decreasing function of wavelength), so indeed, visible light has more entropy than infrared.
