The article doesn't provide very much detail, but it's absolutely possible to absorb multiple low-energy photons and emit fewer higher-energy ones, see e.g. https://en.wikipedia.org/wiki/Second-harmonic_generation – and apparently carbon nanotubes can do this as well.

Critically these photons are not heating up the material. It’s like saying photons reflecting off a mirror heat it. No, the photons that are not reflected do heat the mirror, but not the reflected ones. (At least mostly.)

You're correct, that was sloppy wording on my part.
