While true of normal solar cells, I seem to recall that there are also high efficiency cells designed to be used with solar concentrators. I'm guessing that these will also function at boiling water temperatures. Is this not the case? >Hello Robin > >To store heat economically they can not use water heated by the >PV cells, bcs these cells have to be as cool as possible to work >efficiently. >By concentrating the rest of the direct sunlight on a thermal absorber >it is possible to get much higher temperatures to store heat effectively, >while keeping the >solar cells at a much lower temperature > >Peter v Noorden [snip] Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
