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.

Book Radiation Damage in Silicon Solar Cells from 4 6 mev Proton Bombardment

Download or read book Radiation Damage in Silicon Solar Cells from 4 6 mev Proton Bombardment written by R. L. Statler and published by . This book was released on 1965 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study has been made of the radiation damage in ten types of silicon solar cells as a result of 4.6-Mev proton bombardment. The cells comprised such types as p/n cells, n/p cells with different bulk-resistivities, planar cells as a function of short-circuit current, maximum power output, minority-carrier diffusion length, and photovoltaic spectral response. The p/n cells were found to be more sensitive to radiation damage than any type of n/p cell in this study. In the n/p cells, there is a definite trend toward increasing radiation resistance accompanying increasing values of bulk resistivity, up to 10 ohm-cm. The drift-field solar cells exhibit a further improvement in radiation resistance beyond that of the other types of n/p cells.

Book Proton Electron Damage Ratios for Some Violet Black and Thin Silicon Solar Cells

Download or read book Proton Electron Damage Ratios for Some Violet Black and Thin Silicon Solar Cells written by M. W. Walkden and published by . This book was released on 1979 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to determine their proton to electron damage ratios, four different types of modern silicon solar cell have been subjected to 1 MeV electrons and protons in the energy range from 2-50 MeV, followed at each irradiation stage by an exposure to photon irradiation. The cells included non-reflecting and violet cells of normal (200-250 micrometer) thickness and a thin (50 micrometer) cell. Cell performance measurements were made on new and irradiated cells at room and at elevated temperatures to obtain the proton damage ratios and to ascertain whether these were temperature dependent. It was found that the proton damage ratio of one type of cell was approximately one half of that of the other three types. It was also found that the proton damage ratio for this type of cell was independent of temperature, which was not the case with the other types. One cause of these differences is attributed to photon induced changes in solar cell performance following electron and proton irradiation for the particular material from which this type of cell is made.
