Development and Characterization of III-V/Si Multijunction Photovoltaics for Space Application

III-V/Si dual junction (2J) tandem photovoltaics with potential for eventual application to (aero)space deployment have been under development. Full 2J tandem devices with 16-18% AM0 efficiency have been demonstrated. Temperature dependent LIV and initial characterization related to space applications have also been conducted. Further development of the 2J tandem subcomponents offer a promising pathway to tandem AM0 efficiencies of >25%.
