Abstract :
Silicon solar cells for use in space undergo annealing procedures during fabrication in order to improve their performance. During their operation they are subject to temperatures that can range from -200°C to +200°C. The impact of annealing procedures and temperature variations on the lifetime of minority carriers in the bulk of a silicon solar cell which will be used in the solar cell experiment of the first Brazilian satellite is studied. The solar cell fabrication and the annealing procedures adopted are discussed. The lifetime measurements are presented, and the results are analyzed
