Abstract
Dual junction solar cells are used in space applications for their high efficiency. In this thesis, we model an indium gallium phosphide/gallium arsenide dual-junction solar cell. The solar cell is modeled using Silvaco ATLAS software. Solar cell layer thicknesses and doping concentrations were varied to find optimum efficiency parameters for the solar cell under a variety of radiation conditions. These radiation conditions mimic the damage done at various orbits around Earth for an arbitrary mission length of 12 years. The optimization process resulted in an improved efficiency of 15.1% to 22.4%.
