Hyperion exfoliation has some potential with Silicon PV but is only one step in a new PV cell fab line that would need to be developed. So by itself it is only proof of concept. I have never seen what size it can process..4", 5" and 6" are common sizes for PV cells. The thin exfoliated sheets need to be handled, laminated to a carrier and have collectors and buss bars added and strung together. This is way outside of GT's core competencies and would need team with a PV mfgr to develop....a lot of time and money and outside of any GT recovery time line that I can see. Also the economics of Hyperion is not known....to the outside world. What is the process time per cell and how long to prepare the exfoliated surface for another run. Being technically possible and economically viable are quite different.
