METHOD FOR PRODUCING A PHOTOVOLTAIC CELL HAVING A HETEROJUNCTION, AND RESULTING PHOTOVOLTAIC CELL

摘要

The invention relates to a method for producing a photovoltaic having a heterojunction cell comprising the following consecutive steps: providing a substrate (1) made of a semiconductor crystal material, doped with a first type of doping and provided with a first main surface; depositing a first layer (2) made of an intrinsic amorphous semiconductor material onto said first main surface of the substrate (1); and forming a second layer (5) made of an amorphous semiconductor material on the first layer (2). The method comprises depositing a barrier layer (4) between the first layer (2) and the second layer (5), said barrier layer (4) being of a different nature than those of the first (2) and second (5) layers, and comprises doping the second layer (5) by means of ion implantation.
