It's an interesting idea, I am simply mentioning the practical limitations.
At this point it's a question of how cheaply they can scale it up and how much you can improve the efficiency. Looking at some of their numbers they block ~30+% of the light to gain ~1.3% of the energy you are better off with smaller windows and a high efficiency solar cell around the window. AKA 10% smaller windows block 10% of the light + a 20% efficient solar cell = 2% efficiency. Granted, there is probably a market even in it's current state.

The idea is that, since you already need an anti-reflective coating to block IR light, it might as well be a coating that can scavenge a bit of the incident power instead of sending it all back into space.
