Book excerpt: This report describes the phase II efforts in developing high efficiency GaAs-ON-Ge solar cells for enhanced survivability, ruggedness, and reduced weight over conventional devices. This work emphasizes efforts to improve the cell performance from phase I, initial testing of the cells, and fabrication of a module for space flight testing. The specific goals for the program are: An Air Mass Zero (AM0) conversion efficiency of 18% for beginning-of-life (BOL) at 27 + or - 2 C; An AM0 conversion efficiency of 13.5% at 27 + or - 2 C after exposure to 5 x 10 to the 15th power (MeV) electrons/sq.cm.; A cell weight not to exceed 0.05 grams per square centimeter of cell area. Keywords: Gallium arsenides; Germanium substrates. (AW).

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 excerpt: An abbreviated program to design and develop a thin, low-cost GaAs solar cell for space applications is described. Due to funding limitations, the scheduled four-year program was terminated at the two-year point. Several growth runs utilizing the metal organic-chemical vapor phase (MO-CVD) epitaxial process were made in an attempt to optimize the solar cell structure. Both p/n and n/p growths were made with varying emitter thickness and doping levels. Cell thinning for selected cells was successful to less than 10 microns using a special stop-etch technique. These cells were covered prior to thinning to provide strength and reduce the probability of breakage. (Author).

This book was released on 2021-03-24 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for electronic devices for private and industrial purposes lead designers and researchers to explore new electronic devices and circuits that can perform several tasks efficiently with low IC area and low power consumption. In addition, the increasing demand for portable devices intensifies the call from industry to design sensor elements, an efficient storage cell, and large capacity memory elements. Several industry-related issues have also forced a redesign of basic electronic components for certain specific applications. The researchers, designers, and students working in the area of electronic devices, circuits, and materials sometimesneed standard examples with certain specifications. This breakthrough work presents this knowledge of standard electronic device and circuit design analysis, including advanced technologies and materials. This outstanding new volume presents the basic concepts and fundamentals behind devices, circuits, and systems. It is a valuable reference for the veteran engineer and a learning tool for the student, the practicing engineer, or an engineer from another field crossing over into electrical engineering. It is a must-have for any library.
