Book Radiation Effects on A1GaAs GaAs Solar Cells Using 0 9 3 0 MeV Protons and 1 0 1 4 MeV Electrons

Download or read book Radiation Effects on A1GaAs GaAs Solar Cells Using 0 9 3 0 MeV Protons and 1 0 1 4 MeV Electrons written by L. F. Lowe and published by . This book was released on 1977 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum gallium arsenide solar cells were irradiated with 1.0 and 1.4 MeV electrons, and with 0.9 and 3.0 MeV protons to determine radiation sensitivity. Electron fluences ranged from 1 x 10 to the 14th power to 3 x 10 to the 16 power electrons, 1 sq cm, and proton fluences from 5 x 10 to the 10 power to 2.7 x 10 to the 12th power/sqcm. A solar simulator and a tungsten lamp were used to evaluate changes in the current-voltage characteristics curves. In most cases, AlGaAs solar cells showed a greater resistance to radiation than silicon cells.

Book A Simple Model of Space Radiation Damage in Gaas Solar Cells

Download or read book A Simple Model of Space Radiation Damage in Gaas Solar Cells written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-20 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple model is derived for the radiation damage of shallow junction gallium arsenide (GaAs) solar cells. Reasonable agreement is found between the model and specific experimental studies of radiation effects with electron and proton beams. In particular, the extreme sensitivity of the cell to protons stopping near the cell junction is predicted by the model. The equivalent fluence concept is of questionable validity for monoenergetic proton beams. Angular factors are quite important in establishing the cell sensitivity to incident particle types and energies. A fluence of isotropic incidence 1 MeV electrons (assuming infinite backing) is equivalent to four times the fluence of normal incidence 1 MeV electrons. Spectral factors common to the space radiations are considered, and cover glass thickness required to minimize the initial damage for a typical cell configuration is calculated. Rough equivalence between the geosynchronous environment and an equivalent 1 MeV electron fluence (normal incidence) is established. Wilson, J. W. and Stith, J. J. and Stock, L. V.
