>Lunt said more work is needed in order to improve its energy-producing efficiency. Currently it is able to produce a solar conversion efficiency close to 1 percent, but noted they aim to reach efficiencies beyond 5 percent when fully optimized. The best colored LSC has an efficiency of around 7 percent.

By contrast, conventional rooftop solar is about 18-23% efficient and you need a whole roof of those (often more) to power your house.

I don't think this would provide more than a tiny trickle of electricity, and probably at quite high cost.
