OK, take that Fresnel lens that you were using to melt pennies and then focus it on a PV cell that is also made of metal. What might be the expected response? The science in this case is making PV cells that can handle the intense heat.

That makes sense. If I understood everyone clearly, it’s not the idea to use a fresnel, it’s the fact that we just haven’t had anything capable of withstanding those temperatures and still allowing for the piezoelectric effect to happen.
