    Low cost silicon solar arrays (1975)
    In:  CASI
    Details
    Publication Date: 2016-06-07
    Description: The economic production of silicon solar cell arrays circumvents p-n junction degradation by nuclear doping, in which the Si-30 transmutes to P-31 after thermal neutron capture. Also considered are chemical purity specifications for improved silicon bulk states, surface induced states, and surface states.

    Silicon Sheet Quality is Improved By Meniscus Control (1983)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Better quality silicon crystals for solar cells are possible with instrument that monitors position of meniscus as sheet of solid silicon is drawn from melt. Using information on meniscus height, instrument generates feedback signal to control melt temperature. Automatic control ensures more uniform silicon sheets.

    Solar photovoltaics - An aerospace technology (1977)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: Specific problems affecting the development of low-cost silicon solar array power sources are discussed, taking into account the potential of realizing less than $0.50/per peak watt of silicon solar array technology. A utilization of less expensive processes for the manufacture of pure silicon and more economical procedures of silicon crystal and wafer production appear desirable. Attention is given to a sheet growth process example and a concept of pulsed processing for automated cell production.
