Abstract
A major task in future developments of GaAs space solar cells is to increase the power to area ratio. In this work, high performance in a new triple heterojunction AlGaAs-GaAs space solar cell is obtained by applying antireflection coating with optimum thicknesses. The effects of single and double antireflection coatings on the output characteristics are presented. The reflection from the multiple interfaces through the cell itself is taken into consideration in the optimisation calculations. The use of MgF/sub 2//ZnS as a double antireflection coating for the cell gives an efficiency of 22.101% at AM0.
