High Temperature Solar Cell Contacts.
Abstract
Gallium arsenide solar cells may be subjected to extreme temperature excursions as high as 600 C during processing steps and while operating in space orbits. To prevent solar cell failure during fabrication and its operating life, the electrical contacts to the active semiconductor material must remain electrically and chemically stable during these high temperature excursions. The objective of this effort is to develop an electrical contact material to the gallium arsenide solar cell which will survive temperatures up to 600 C (873K) for periods up to 15 minutes. During this contracting period a thermodynamic phase equilibrium computer model was developed which calculates the liquidus and solidus phase boundaries of metal-Ga-As systems of interest to determine their potential high temperature stability.
