Let's just call it PUREVAP Si as it just needs a maximum impurity content of 0.3ppm Boron & 0.6ppm Phosphorus, minus all other elements that are removed through segregation, plasma treatment, vacuum refinement & carbothermic reduction. With that Silicon they would then be able to grow a Cz ingots that would then be cut into wafers for solar panels and produce up to a 18% solar energy conversion with the right dopents. Just from my research though. GOOOOOO HPQ!!!!!!
In addition to solar use, there is a world market for -3N Si that is not being discussed or factored in imo:
