Abstract
The present invention relates to a multi-layer material comprising an assembly of layers, called “front layers”, capable of forming a front photovoltaic cell, and an assembly of layers, called “rear layers”, capable of forming a rear photovoltaic cell, wherein the front layer assembly and the rear layer assembly are electrically insulated by an insulating layer of epitaxial material.
Claims22
A Multi-layer material comprising:
- an assembly of layers, called “front layer assembly” forming a front photovoltaic cell comprising at least one combination of layers of a first material and of a second material forming an heterojunction comprising a chalcogenide or perovskite layer, and a back contact layer of a III-V semiconductor compound;
- and
- an assembly of layers, called “rear layer assembly” forming a rear photovoltaic cell comprises at least monocrystalline silicon,
- wherein the front layer assembly and the rear layer assembly are electrically insulated by an insulating layer of epitaxial material, and form a tandem photovoltaic cell having a vertical stacking of said silicon cell and said heterojunction comprising at least a chalcogenide or perovskite layer and said back contact layer of a III-V semiconductor compound, wherein said chalcogenide or perovskite layer is epitaxial.
