MULTIPLE-JUNCTION PHOTOVOLTAIC CELL BASED ON ANTIMONIDE MATERIALS

摘要

The invention relates to a photovoltaic cell that can be used under high levels of solar concentration (≥1000 suns). The cell according to the invention consists of a cell comprising at least one junction produced on a substrate based on gallium antimonide, said at least one junction comprising two alloys based on an antimonide material (Ga1-xAlxAsySb1-y) lattice-matched on the substrate GaSb. If there are several junctions, two neighbouring junctions are separated by a tunnel junction.
