Book Synopsis Radiation Effects on A1GaAs/GaAs Solar Cells Using 0.9-3.0 MeV Protons and 1.0-1.4 MeV Electrons by : L. F. Lowe

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 Synopsis A Novel Approach to Modeling the Effects of Radiation in Gallium- Arsenide Solar Cells Using Silvaco's ATLAS Software by : Aaron L. Crespin
Download or read book A Novel Approach to Modeling the Effects of Radiation in Gallium- Arsenide Solar Cells Using Silvaco's ATLAS Software written by Aaron L. Crespin and published by . This book was released on 2004-09-01 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of radiation in GaAs solar cells has been extensively researched and the results of numerous investigation have yielded a considerable amount of information about the degradation in irradiated solar cells. This thesis establishes a novel method in which to use Silvaco's physically-based device simulator, ATLAS, to model the effects of radiation on solar cell output characteristics. A virtual model representing a single junction GaAs solar cell was created in ATLAS. The effects of radiation were modeled using carrier trapping statements representing the defects associated with various fluence levels of 1 MeV electron radiation which were characterized with Deep Level Transient Spectroscopy techniques. The resulting output characteristics of the virtual solar cell, illuminated with a simulated AM0 spectrum, were compared to published experimental measurements for GaAs solar cells of the same dimensions. The virtual solar cell demonstrated a good correlation between the measured and virtual solar cell output characteristics and accurate representation of the spectral response. Complete ATLAS and MATLAB codes are included in appendices.

Book Synopsis GAAS Solar Cell Radiation Handbook by : B. E. Anspaugh
Download or read book GAAS Solar Cell Radiation Handbook written by B. E. Anspaugh and published by CreateSpace. This book was released on 2014-10-25 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gallium Arsenide (GaAs) has been of interest as a photovoltaic material for many years. This interest arises primarily for three reasons. First, the bandgap of 1.42eV at 300 K is very nearly ideal for a photovoltaic device operating in our solar spectrum. Second, GaAs solar cells should be capable of operating at higher temperatures than silicon (Si) cells. Third, GaAs solar cells are expected to be very radiation resistant. This handbook provides a history of GaAs solar cell development; Photovoltaic equations are described along with instrumentation techniques for measuring solar cells; Radiation effects in solar cells, electrical performance, and spacecraft flight data for solar cells are discussed; and the space radiation environment and solar array degradation calculations are addressed.

Book Synopsis Radiation Effects on Multi-Junction Solar Cells by : Tommy L. Fifer
Download or read book Radiation Effects on Multi-Junction Solar Cells written by Tommy L. Fifer and published by . This book was released on 2001-12-01 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The GaInP2/GaAs/Ge monolithic high efficiency triple junction cell is the state of the art multijunction solar cell for space applications. Numerous labs have undertaken investigation into the stability of GaInP2/GaAs/Ge in response to electron radiation. Electron radiation experiments have shown that the degradation of GaInP2/GaAs/Ge solar cells is mainly caused by a decrease of the short circuit current (Isc). The investigation and interpretation of the damage mechanism from electron irradiation in Spectrolab's GaInP2/GaAs/Ge triple junction cell is the purpose of this thesis. Current voltage characteristics were measured to establish beginning of life (BOL) parameters of the solar cells and the changes that occur due to irradiation (EOL).

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.

Available in PDF, EPUB and Kindle. Book excerpt: Ten silicon solar cells were irradiated by 100-curie Co 60 gamma ray source to a dose of 10 to the 7th power r. In-situ measurements of the open-circuit voltage and short-circuit current were obtained. Calculations to predict the performance of silicon solar cells under irradiation were made on the basis of known properties of silicon and on the basis of models of radiation damage in solids. Calculated and experimental results were compared. The electrical characteristics of the solar cells were measured as a function of temperature before and after irradiation. The performance of a silicon solar cell power supply in radiation fields is discussed. (Author).
