Abstract
(EN)
A photovoltaic cell device, e.g., solar cell, solar panel, and method of manufacture. The device has an optically transparent substrate comprises a first surface and a second surface. A first thickness of material (e.g., semiconductor material, single crystal material) having a first surface region and a second surface region is included. In a preferred embodiment, the surface region is overlying the first surface of the optically transparent substrate. The device has an optical coupling material provided between the first surface region of the thickness of material and the first surface of the optically transparent material. A second thickness of semiconductor material is overlying the second surface region to form a resulting thickness of semiconductor material.

La présente invention concerne un dispositif de cellule photovoltaïque, par exemple, une cellule solaire, un panneau solaire, et son procédé de fabrication. Le dispositif comporte un substrat optiquement transparent comprenant une première surface et une seconde surface. Une première épaisseur de matériau (par exemple, un matériau semi-conducteur, un matériau monocristallin) présentant une première zone superficielle et une second zone superficielle est incluse. Dans un mode de réalisation préféré, la zone superficielle est sus-jacente à la première surface du substrat optiquement transparent. Le dispositif comporte un matériau de couplage optique prévu entre la première zone superficielle de l'épaisseur de matériau et la première surface du substrat optiquement transparent. Une seconde épaisseur de matériau semi-conducteur est sus-jacente à la second zone superficielle pour obtenir la formation d'une épaisseur de matériau semi-conducteur.
