This article presents a complete plasma etching process to etch high aspect ratio patterns on
III-V/Ge solar cell heterostructure with low damage for the fabrication of multijunction solar …

Multijunction solar cells must be electrically isolated from one to another at the end of the
fabrication process; a step known as mesa isolation. In this study, three different techniques …

Summary Three-dimensional (3D) interconnects increase chip power density and enable
miniaturization. Photonic chips require new processes to enable transitioning to 3D …

Solar cell efficiency can be associated with the ability of the solar cell to produce the
maximum amount of electricity from a light energy source. There are many uses of multi …

Improvement of triple-junction (3J) III-V/Ge solar cells efficiency is hindered by the low
current produced by the top and middle cells relative to the bottom cell (Ge). This can be …

In the case of the fabrication of flexible solar cells based on the inverted metamorphic
multijunction (IMM) structure, the conventional high-temperature annealing will result in the …

Lattice matched III-V/Ge solar cells are mainstream for Concentrator PhotoVoltaics (CPV).
