โœฆ Synopsis

Electron beam-induced current (EBIC) measurements have been made on a variety of GaAs and InP single-crystal space solar cells. Plots of the EBIC gain against beam voltage for homoepitaxial GaAs, heteroepitaxial GaAs/Ge and InP solar cells, are presented. Direct correlation between the photovoltaic performance of the cells and the EBIC gain measurements is demonstrated. Quantifiable deterioration of the diffusion lengths, determined by applying Monte Carlo techniques, is evident after irradiation of cells with high-energy protons to simulate the environment in space.

The Kelvin method and Auger effect have been used to study the efficiency of thermal annealing in situ under H2 at 350 and 650 ยฐC of germanium substrates, chemically etched with CP4 and HNO3-HF, for use in multicolor solar cells. This is done by specifying the state of the surface and evaluating the
