The theoretical maximum efficiency of a single-junction solar cell is about 33.7%, known as the Shockley-Queisser limit. However, using multiple junctions can increase this limit, with some advanced designs potentially reaching efficiencies of up to 68.7% under ideal conditions.
If we can solve the 15-20% efficiency loss after 10 years (measured from install) that will go a long ways. Like anything else, technology advances. There is also the lattice electron entrapment that seems to happen after hours that causes a drop off. Problems for smarter minds than mine. But it seems to boil down to cost vs return.
Unless we make the hop to small modular nuclear, electric rates won’t be dropping anytime soon
