The ZTJ cells, CICs (Coverglass-Interconnected-Cell) and solar panels have also been characterized and qualified to both the AIAA-S-111 and AIAA-S-112 standards.
What is the risk of irradiated solar cells?
The likelihood of this risk is based on the safety record of exposing solar cells to radiation. The consequence is based on the consequences of exposure to irradiated solar cells that have not been sufficiently “cooled.” The consequence could also be increased to a 5 due to the possibility of increasing the chances of a life ending cancer.
