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.

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.

A Multi-layer material comprising:
- a layer of at least one monocrystalline material having a front face and a rear face;
- a combination of heterojunction layers comprising a first material and a second material, wherein the heterojunction comprises a front face and a rear face;
- a layer, comprising a front face and a rear face, referred to as the back contact of the heterojunction, wherein the front face is in contact with the rear face of the heterojunction, and
- an electrically-insulating layer of epitaxial material having a front face and a rear face, wherein the electrically-insulating layer is arranged between the rear face of the rear layer of the heterojunction and the front face of the monocrystalline material;
- wherein the electrically-insulating layer is in alternating front-side contact with the back contact layer of the heterojunction and the rear face of the heterojunction or an insulating material.
