Title (EN) PHOTOVOLTAIC CELL AND PROCESS FOR MANUFACTURING A PHOTOVOLTAIC CELL
(FR) CELLULE PHOTOVOLTAÏQUE ET PROCEDE DE FABRICATION D'UNE CELLULE PHOTOVOLTAÏQUE
Abstract:
(EN) The invention relates to a photovoltaic cell and to a process for manufacturing a photovoltaic cell comprising: a substrate (1) made of silicon; a network of walls (8) made of a dielectric deposited on the substrate (1), the network of walls (8) made of a dielectric defining cells (6) of square or hexagonal cross-section, there being a buffer layer (B) in each cell (6); at least one p-n junction (J1, J2) in each cell (6), the p-n junction (J1, J2) being deposited on the buffer layer (B), the p-n junction (J1, J2) including a semiconductor having a lattice parameter that is different from that of silicon, and the buffer layer (B) having a lattice parameter that is identical to that of the p-n junction (J1, J2) deposited on this buffer layer (B); and a metal grid (11) that is aligned with at least some of the walls (8).
(FR) L'invention concerne une cellule photovoltaïque et un procédé de fabrication d'une cellule photovoltaïque comportant: un substrat (1) en silicium; un réseau de murs (8) en matériau diélectrique déposé sur le substrat (1), le réseau de murs (8) en matériau diélectrique définissant des alvéoles (6) de section carrée ou hexagonale, une couche tampon (B) dans chaque alvéole (6); au moins une jonction pn (J1, J2) dans chaque alvéole (6), la jonction pn (J1, J2) étant déposée sur la couche tampon (B), la jonction pn (J1, J2) comportant un matériau semi-conducteur présentant un paramètre de maille différent de celui du silicium, la couche tampon (B) présentant un paramètre de maille identique à celui de la jonction pn (J1, J2) déposée sur cette couche tampon (B); une grille métallique (11) alignée avec au moins une partie des murs (8).
