I found the Zenith system (1000x suns in a multi junction cell) it's only 22%. That's why they bankrupted... The cell could be 45% efficient, but it probably don't get so much due the temperature it works, since it need to keep water hot, and so thye cell, reducing cell efficience to electric energy.

I still would like tho see a system of concentrated photovoltaics, that split the ligh spectrum, sending the infrared light to heat water and the other wavelenghts to multi junction cells.
