Use of displacement damage dose in an engineering model of GaAs solar cell radiation damage

Abstract

In this study we have combined a method of calculating radiation induced damage to solar cells using Non‐Ionizing Energy Loss (NIEL), with models of Earth orbiting radiation in arbitrary orbits, to assess the lifetime of solar cells. This paper provides a comparison of the NIEL technique to results from the JPL Radiation Handbook, and to actual space experimental damage results. In addition, we discuss ways of extending the calculation to newer solar cell materials, as well as environments outside of the Earth's orbit. Copyright © 2000 John Wiley & Sons, Ltd.

SAVANT analysis of the microelectronics and photonics testbed solar cell data

“…While this result is within the stated uncertainties of the environment models, 9 analyses of other space datasets have produced better agreement between the SAVANT estimates and measured on-orbit data. 10,11 One difference with MPTB is that it is, by far, the longest mission considered for SAVANT testing. There are over four years of MPTB data as compared to less than two years for the next longest mission.…”

Modeling solar cell degradation in space: A comparison of the NRL displacement damage dose and the JPL equivalent fluence approaches†

“…The NRL approach is currently being incorporated at NASA Glenn Research Center into a`user-friendly' computer code called the Solar Array Veri®cation and Analysis Tool (SAVANT 10,25 ). SAVANT combines an orbit generator with the NASA-developed AE8 electron and AP8 proton radiation environments, and the IGRF95 geomagnetic ®eld model to determine the incident differential electron and proton¯uence spectrum for any desired orbit.…”
