Martin Marietta Corporation's design of a second generation concentrating photovoltaic module is described. The passively cooled 13-kg module uses 2 columns of 7 point focus Fresnel lenses that are each 20.7 cm by 20.7 cm, and 14 planar junction silicon cells. The geometric concentration is 84X. Martin Marietta fabricated five prototype modules and shipped three to Sandia for testing. The modules' peak efficiency was 14.1% which is the highest to date for a module using silicon cells.
