우주선용 GaAs/Ge 태양전지에 관한 연구
Study on GaAs/Ge Solar Cell for Space Use
초록
The interests on GaAs solar cell grown on Ge substrates as an alternative of GaAs substrate arises from its very close lattice parameters, very small difference in thermal expansion coefficients, and much higher fracture toughness between GaAs and Ge. In addition, for many space power application, it would be a most attractive solar cell with high radiation resistance of GaAs and high reliability for the reverse current damage of Ge, and expecting the theoretical efficiency limit of the tandem GaAs/Ge solar cell is 34% under 1 Sun, AM 0, and 28
