PHOTOVOLTAIC CELL HAVING A HETEROJUNCTION AND METHOD FOR MANUFACTURING SUCH A CELL |
摘要 |
The invention relates to a photovoltaic cell having a heterojunction, including a doped substrate (1), in which: a first main face (1A) of said substrate is covered with a passivation layer (2A), a doped layer (3A) of the type opposite to the substrate and forming the transmitter of said cell; the second main face (1B) of said substrate is covered with a passivation layer (2B), a doped layer (3B) of the same type as the substrate defining a repulsing field for the minor carriers of the substrate; characterized in that: the material of the passivation layer (2A) on the transmitter (E) side is selected so as to have a lower potential barrier for the photo-generated minor carriers than for the major carrier of the substrate; and in that the material of the passivation layer (2B) on the side of the repulsing field (BSF) is selected so as to have a lower potential barrier for all the photo-generated major carriers than for the minor carriers of the substrate. |
