That is, in order to connect one back electrode 20 of the adjacent photoelectric conversion cell 50 and the other transparent electrode layer 12, a plurality of connection members 26 are provided on the side wall on the first slit S1 side of the fourth slit S4. Thereby, compared with the case where one back electrode 20 and the other transparent electrode layer 12 of the adjacent photoelectric conversion cell 50 are connected by one connection member, the amount of the material used for the connection member can be reduced. Thus, the material cost of the photoelectric conversion device can be reduced.
- connection member 26 which connects the several photoelectric conversion cell 50 formed on the big board
- the connection member 26 is formed by the sputtering method, it is difficult to form the plurality of connection members 26 uniformly on a large substrate.
- a mask is used to form the plurality of connection members 26, the material for the connection members 26 that is simply sputtered on the entire surface of the substrate 10 is required, and the amount of material used for the connection members 26 cannot be reduced. It was.
- connection member 26 in the case of forming the connection member 26 using a conductive paste, a plurality of connection members 26 having a uniform film thickness can be formed by an easy method such as a screen printing method even on a large substrate. it can. Further, the connection member 26 can be formed with a small amount of material, and the material cost of the photoelectric conversion device can be reduced.
- the present invention can be used for photoelectric conversion devices such as solar cells.

Abstract
L'invention concerne un convertisseur photoélectrique (100) comprenant une pluralité de cellules de conversion photoélectrique (50), chacune étant obtenue par superposition d'une couche d'électrode transparente (12), d'une première couche de conversion photoélectrique (14), d'une couche intermédiaire (16), d'une seconde couche de conversion photoélectrique (18) et d'une électrode postérieure (20), dans l'ordre indiqué, sur un substrat (10). L'électrode postérieure (20) d'une cellule de conversion photoélectrique (50) adjacente et la couche d'électrode transparente (12) d'une autre cellule de conversion photoélectrique (50) adjacente sont connectées ensemble par plusieurs liaisons.
