High-Energy Electron Irradiation of High-Efficiency Thin-Film Gallium Arsenide Solar Cells

Abstract

The electrical power supplied to satellites will continue to be provided by solar cells for the foreseeable future and new technologies and better methods of production for these cells will continue to be developed. Additionally, the space environment within the Earths radiation belts and the effect of the radiation on solar cells within this environment is well documented. The effects of radiation on solar cells outside this environment with the use of an 8-MeV electron beam was investigated. Thin-film high-efficiency gallium arsenide test devices were characterized, and an analysis of the thin-film devices performance post-irradiation was conducted via illuminated DC current-voltage and external quantum efficiency measurements. The results of this analysis showed a drastic reduction in device short circuit current of The purpose of the PCCTC is to accelerate the development of novel therapeutics for prostate cancer patients, both by bringing our own areas of expertise and contributing substantially to the activity of the consortium. Scope: The scope of the involvement of UCSF is to develop protocols for the consortium in the areas of immunotherapies, secondary hormonal signaling, chemotherapy, and PARP inhibitors. Results: During the reporting period, 1 LOI was presented to the PCCTC Coordinating Center, and 32 patients were accrued to 7 PCCTC clinical trials. over 95% by a total electron fluence of 10 (expn 16) cm (expn -2).
