Intuitively I would guess theres not a benefit and probably a net negative.
– The PV would lose efficiency because of extra heat and would potentially have a shorter life.
– The surface area exposed to the sun of the magnifying lens would need to be at least the same size as the PV would be.
I expect with all the money going into research in this area, its likely someone has written a paper on it at _some_ point – and no one has jumped on that bandwagon.
Also the price of PVs has come down SO much over the last few years, that they’re a relatively small part of the cost of a solar installation. I’ve seen numbers suggesting the PVs are only 20% of the whole system installation cost.
