摘要

未来发展砷化镓空间太阳能电池的主要任务是提高功率面积比。在这项工作中，通过应用最佳厚度的增透涂层，在新型三异质结AlGaAs-GaAs空间太阳能电池中获得了高性能。介绍了单增透膜和双增透膜对输出特性的影响。在优化计算中考虑了从多个接口通过单元本身的反射。使用MgF/sub //ZnS作为电池的双增透涂层，在AM0下的效率为22.101%。

Design of antireflection coatings for triple heterojunction AlGaAs-GaAs space solar cells

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.
