Title (EN) PHOTOVOLTAIC CELL HAVING A STRUCTURED BACK SURFACE AND ASSOCIATED MANUFACTURING METHOD
(FR) CELLULE PHOTOVOLTAÏQUE À FACE ARRIÈRE STRUCTURÉE ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract: front page image
(EN)The invention relates to a photovoltaic cell (1) which includes at least one wafer (2) of a semi-conductor material, with a front surface (21) intended for receiving incident light and a back surface (22) opposite said front surface, as well as to methods for manufacturing said photovoltaic cell. The back surface (22) includes an electric contact (32) and a structure (4), referred to as an optical structure, which is discrete and capable of redirecting the incident light towards the core of the wafer.
(FR)L'invention concerne une cellule photovoltaïque (1) comprenant au moins une tranche (2) de matériau semi-conducteur, avec une face avant (21) destinée à recevoir la lumière incidente et une face arrière (22) opposée à ladite face avant, ainsi que des procédés de réalisation de cette cellule photovoltaïque. La face arrière (22) comprend un contact électrique (32) et une structure (4) dite structure optique, discrète et susceptible de rediriger la lumière incidente vers le cœur de la tranche.
