The interplay with Soliance and GSL technology re perovskite on metal will make it irresistible to the likes of Tata who have shown interest in the concept. Mind you, IMHO trying to make it compatible with roll to roll rather than printing onto a finished sheet is a recipe for a world of pain.
Yes, Perovskites describe a near ideal solar energy capturing structure, not a fixed way of achieving it, so there are a massive amount of different technologies, just as there are different models of cars on the road. But ask yourself who has working panels close to large scale practical manufacture? GSL, that's who. They can change the mix on the fly as new improved recipes emerge, they will be attracted like flies to GSL as a conduit to fast research payback rather than spend countless years and outlaying megabucks getting to the same stage.
Re Turkey, to be fair to RC, both local and world events have thwarted his best intentions. When he somehow breaks the watershed funding logjam, other funds will flow forth in a gush
