PhD Defense: 'III-V multijunction solar cells contributions in the renewable energy engineering'

The focus of this research is the advancement of vertical multijunction (VMJ) gallium arsenide (GaAs) solar cells that are essential for ultra-high concentration photovoltaic (UHCPV) systems. The advantages of VMJ solar cells are their high energy conversion efficiency, robustness against space radiation, and suitability for space applications.
