Gamma radiation effects in silicon solar cells

Abstract : 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)
