Abstract[English]
A tandem solar cell (100) includes a first-type base (102) having first and second surfaces (102A, 102B), opposite to each other, a second-type layer (108) formed on the second surface (102B) of the first-type base (102), wherein the first-type is one of n- or p-type and the second-type is another of the n- or p-type, and the second-type layer (108) and the first-type base (102) form a first pn junction, and an additive-treated perovskite layer (124) formed on the first surface (102A) of the first-type base (102), wherein the additive-treated perovskite layer (124) and the first-type base (102) form a second pn junction. The additive-treated perovskite layer (124) has an organic additive (310) that includes carbon, hydrogen and nitrogen, and is distributed at borders between grains (Gi) of the perovskite layer. The additive-treated perovskite layer (124) includes a perovskite material that has a band gap equal to or larger than 1.65 eV.[French]
Une cellule solaire en tandem (100) comprend une base de premier type (102) ayant des première et seconde surfaces (102A, 102B), opposées l'une à l'autre, une couche de second type (108) formée sur la seconde surface (102B) de la base de premier type (102), le premier type étant l'un d'un type n ou d'un type p et le second type étant un autre du type n ou du type p, et la couche de second type (108) et la base de premier type (102) formant une première jonction pn, et une couche de pérovskite traitée par additif (124) formée sur la première surface (102A) de la base de premier type (102), la couche de pérovskite traitée par additif (124) et la base de premier type (102) formant une seconde jonction pn. La couche de pérovskite traitée par additif (124) a un additif organique (310) qui comprend du carbone, de l'hydrogène et de l'azote, et est distribué au niveau de bordures entre les grains (Gi) de la couche de pérovskite. La couche de pérovskite traitée par additif (124) comprend un matériau pérovskite qui a une bande interdite égale ou supérieure à 1,65 eV.
