  44.7% actually http://upload.wikimedia.org/wikipedia/commons/a/a5/PVeff%28rev141208%29.jpg http://upload.wikimedia.org/wikipedia/commons/a/a5/PVeff%28r... http://en.wikipedia.org/wiki/Solar_cell_efficiency http://en.wikipedia.org/wiki/Solar_cell_efficiency

    Ah, nice graph! Thanks for posting! I was unaware about the steady progress. Still far away from the 90+% thermal efficiency that is possible with solar heating. My hopes on photovoltaics are on the relatively new contender Perovskite. Really nice to see the steep progress in efficiency there.

      The theoretical limit for solar cells is much lower than 100%: http://en.wikipedia.org/wiki/Shockley%E2%80%93Queisser_limit http://en.wikipedia.org/wiki/Shockley%E2%80%93Queisser_limit
