Definitions

  • the present invention relates to a tandem solar cell and a method for manufacturing a tandem solar cell.
  • Solar cell modules are known in which multiple solar cells are connected by wiring members such as tabs.
  • Known solar cell types include crystalline silicon solar cells, which use a crystalline silicon substrate as the photoelectric conversion layer, and thin-film solar cells, which use an inorganic thin film such as an amorphous silicon thin film as the photoelectric conversion layer.
  • thin-film solar cells are perovskite thin-film solar cells, which use a perovskite thin film, an organic thin film (more specifically, an organic/inorganic hybrid thin film), as the photoelectric conversion layer.
  • Patent Document 1 discloses a tandem solar cell that includes a bottom cell (first photoelectric conversion unit) that contains a crystalline silicon substrate as the photoelectric conversion layer, and a top cell (second photoelectric conversion unit) that contains a perovskite thin film as the photoelectric conversion layer.
  • tandem solar cells include two-terminal types, in which the top and bottom cells are connected in series, and four-terminal types, in which electricity is extracted separately from the top and bottom cells.
  • three-terminal tandem solar cells have been devised that combine the advantages of these two-terminal and four-terminal types and have the potential to further improve photoelectric conversion efficiency (see, for example, Patent Document 2).
  • a slit-shaped electrode for example, is placed on the light-receiving surface side, and a strip-shaped wiring member is connected to this electrode.
  • the tandem solar cell of the present invention is a two-terminal tandem solar cell comprising a first photoelectric conversion unit including a crystalline silicon substrate, a second photoelectric conversion unit arranged closer to the light-receiving surface than the first photoelectric conversion unit and including a perovskite thin film, a first electrode arranged on the light-receiving surface side of the second photoelectric conversion unit, and a second electrode arranged on the back surface side of the first photoelectric conversion unit, and the portion of the perovskite thin film corresponding to the first electrode and the wiring member connected to the first electrode has a higher resistance than the remaining portion of the perovskite thin film.

Abstract

La présente invention propose une cellule solaire tandem dans laquelle une réduction de l'efficacité de production d'énergie peut être atténuée. Une cellule solaire (2) est une cellule solaire tandem à deux bornes comprenant : une première partie de conversion photoélectrique (10) qui comprend un substrat de silicium cristallin (11); une seconde partie de conversion photoélectrique (20) qui est disposée plus loin sur un côté de surface de réception de lumière que la première partie de conversion photoélectrique (10) et qui comprend une couche mince de pérovskite (21); une première électrode (31) disposée sur le côté de surface de réception de lumière de la seconde partie de conversion photoélectrique (20); et une seconde électrode (32) disposée sur un côté de surface arrière de la première partie de conversion photoélectrique (10), la partie de la couche mince de pérovskite (21) qui correspond à la première électrode (31) et un élément d'interconnexion (6) connecté à la première électrode (31) présentant une résistance supérieure à celle d'autres parties de la couche mince de pérovskite (21).
