So how does this efficiency compare to that of silicon based photovoltaics?

“So how does this efficiency compare to that of silicon based photovoltaics?”

It can actually be additive... so together they get near 50% efficiency.

Per the article it is a few percentage points more efficient than the standard silicone panels. It sounds like the major breakthrough beyond a point or two of efficiency is costs and ease to produce.

20 to 27% for the silicon based cells. While these are a bit lower, if they really come out cheaper and can be placed on curved surfaces, it might make sense to be on more roofs. Solar still won’t replace baseload power.. I really hope Trump’s energy initiative puts money into Thorium.
