Engineering360: "New formula boosts bifacial solar cell performance"

So that is it, they develop 20% more than all other monofacial PV? Is that what happens when developing production models? I am interested in the facts, which seem to be missing in this article. I am probably missing the point of it, so I would appreciate any feedback.

BTW, I am a PV Engineering, Procurement and Construction professional, and while we are using some bifacial equipment, we find manufacturers claims to be wildly optimistic, which we have attributed to the surface below these panels. In that case, it may have very little to do with the bifacial technology.
