Concentrated photovoltaics (CPV) provides the highest efficiency among photovoltaic
technologies but remains too expensive to be deployed on a large scale. The miniaturization …

A core issue in concentrator photovoltaic technology (CPV) is the resistive losses in cells
that usually limits the maximum photoconversion efficiency under high concentration. We …

Les dispositifs photovoltaïques, dominés par les panneaux en silicium, ont su évoluer pour
proposer aujourd'hui des coûts d'électricité concurrentiels aux sources fossiles. Parmi les …

Investigation and development of the post-growth technology for fabricating multi-junction
photovoltaic converters based on GaInP/GaInAs/Ge heterostructure has been carried out …

At the end of the fabrication process, multijunction solar cells must be electrically isolated
from one to another; a step commonly known as mesa isolation. In this paper, three different …

In this paper, we present a complete microfabrication process for III-V/Ge triple junction solar
cells with through cell via contacts. This architecture enables the transfer of the front side …
