The idea of a parabolic mirror to focus light onto a small solar panel popped into my mind the other day. I searched Google and this is about the best thing I found-

and

Wouldn't focusing light toward one little panel be way more efficient than the fields of panels that I keep seeing more and more of? It seems to me that the Arizona plant is using the heat from this concentrated light to boil water and turn steam turbines. Good idea but why not instead use the light itself pointed at a photovoltaic cell? Can someone help me make sense of this?
