Title (EN) SOLAR PHOTOVOLTAIC MODULE
(FR) MODULE SOLAIRE PHOTOVOLTAÏQUE
Abstract:
(EN) In the present invention a new solar photovoltaic module is proposed comprising a solar cell comprising a silicon layer having a first (1 a) surface and a second surface (1a) opposite to said first surface. The solar cell further comprises a passivating layer stack (2) comprising a heterogeneous layer (4) arranged on said first surface and/or on said second surface. The heterogeneous layer (4), having a back surface (3) and a front surface (5), comprises a non-conducting matrix (4b) having a refractive index being lower than 3.0. The heterogeneous layer further comprises inclusions 4a of at least one conductive material in said matrix 4b, and at least some of said inclusions (4a) extend from said back surface (3) to said front surface (5) of the heterogeneous layer (4) for electrically connecting the surfaces (3,5) of the heterogeneous layer.
(FR) Dans la présente invention, un nouveau module solaire photovoltaïque est décrit, celui-ci comprenant une cellule solaire comportant une couche de silicium ayant une première surface (1a), et une seconde surface (1b) à l'opposé de ladite première surface. La cellule solaire comprend en outre un empilement de couches de passivation (2), comprenant une couche hétérogène (4), agencé sur ladite première surface et/ou sur ladite seconde surface. La couche hétérogène (4), présentant une surface arrière (3) et une surface avant (5), comprend une matrice non conductrice (4b) possédant un indice de réfraction inférieur à 3,0. La couche hétérogène comprend en outre des inclusions (4a) d'au moins un matériau conducteur dans ladite matrice (4b), et au moins certaines desdites inclusions (4a) s'étendent de ladite surface arrière (3) à ladite surface avant (5) de la couche hétérogène (4) pour connecter électriquement les surfaces (3, 5) de la couche hétérogène.
