Yes, it says it in the abstract, but isn't really given special attention to in the article itself. Looking at the graphic it looks like a fairly normal absorption spectrum for a solar panel without it being specifically tailored to this use-case. It seems like there might still be something won by specifically tailoring it to be complementary to the plant absorption spectrum. On the other hand it might also not be economically viable due to lack of scale and varying requirements for wavelengths between plant species and stages of plant development, which makes some optimizations moot.
