Abstract:

A technique was developed for the accelerated evaluation of silicon solar cells to be used in extended space missions during which weapons environments may also be encountered. Standard NP silicon cells, as well as lithium-doped silicon cells, were used as test samples during the development and verification of the evaluation method. The solar cell damage model developed represents a significant advancement for predicting space performance of solar cells. The model is capable of 1 accounting for the shielding of solar arrays, 2 integrating over the space environment for both protons and electrons, 3 calculating defect densities as a function of position inside the solar cell, 4 calculating the output I-V characteristics of solar cells under a solar illumination spectrum, and 5 accounting for annealing in lithium doped PN solar cells.
