Multi-crystalline silicon-germanium bulk crystal for use as a solar cell and method of making

Image Number 2 for United States Patent #7750232.

A multi-crystalline silicon germanium bulk crystal with microscopic compositional distribution is adapted for use in solar cells to substantially increase conversion efficiency. By controlling the average Ge concentration between 0.1 and 8.0 mole percent, significant improvements are attained with respect to short circuit current density and conversion efficiency.
