This sounds like someone made minute, non-revolutionary advances on standard de-salination and described it as if they were the first person to invent evaporative desalination. People have been doing sun powered desalination for thousands of years.
At small scales.
At large scales, desalination plants use reverse osmosis, which pretty much inherently creates a brine that is released back into the environment. You're not "moving the salt" to any useful industrial process, since it's still rather dilute.
At best, some of those plants use solar power to drive the RO process. But we'd much rather have the electricity to power other things, so a process that uses a non-semiconducting metal surface to perform solar-powered evaporative distillation, without a need to dispose of a brine, and without relying upon solar-electric generation and conversion, is a bigger deal than you make it out to be.
