Bob, The Voc (open circuit) = 2.7V aprox The Isc (short circuit) = 455 mA aprox
The value are aproximate because depends on the technology ATJ, BTJ, ZTJ, MATJ, MBTJ, MZTJ This link show the cells and their datasheets http://www.emcore.com/solar_photovoltaics/space_solar_cells Important, these value are infomation about standars cells, not for the cells with mechanical or electrical anomalies The area is 26.6 cm2 and the size is like a rectangle of 4 x 8 cm (aprox). Enter two cells on each side of the cube.
