    Solar Cells From Metallurgical-Grade Silicon (1982)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Epitaxial deposition produces acceptable solar cells from metallurgicalgrade silicon. Instead of diffusing dopants into silicon to form pn junction, junction is formed by growing epitaxial layer--one having crystal structure continuous with that of substrate--on metallurgical-grade silicon. Less pure forms of silicon, such as metallurgical-grade, are less expensive than semiconductor-grade material and help to lower cost of solar cells.

    High-Efficiency Solar Cells on Low-Cost Substrates (1982)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: High-efficiency solar cells made in thin epitaxial films grown on low-cost commercial silicon substrates. Cost of cells is much less than if high-quality single-crystal silicon were used for substrates and performance of cells is almost as good.
