arbitrary chosen polycrystal
solar cell 100mm x 100mm: 0.47V, max current (short circuit) 2,6A
(, #112135-99)

This is < 1W / 10*10cm, probably << for efficiency (you won't get 2,6A at 

matches the supposed 1000W/squaremeter of ingress solar power which is a rule 
of thumb of meteorologists.

Another module:
70 x 30mm, 3.6V, 27mA nominal current (, 110330-99)
