Abstract[English]
This disclosure relates to a novel hole-collecting laminated electrode presented for perovskite solar cells. The hole-collecting electrode comprises a nanoparticle hole¬ transport layer, and a conductive back sheet, where the gap between them is filled with a conductive adhesive. The application of the back sheet electrode on top of the nanoparticle HTL involves a wet application process, where a conductive adhesive ink is applied, while the conductive back sheet is lying on the HTL, in a way that ink completely dries while the sheet is applied on the surface. The adhesive ink includes a solvent, a binder, a conductive carbon nanoparticle as filler, semiconductor nanoparticles such as metal oxide or chalcopyrite for effective charge transfer, and modifying agents as additives to add additional properties to the ink.[French]
La divulgation concerne une nouvelle électrode stratifiée de collecte de trous présentée pour des cellules solaires en pérovskite. L'électrode de collecte de trous comprend une couche de transport de trous à nanoparticules, et une feuille arrière conductrice, l'espace entre elles étant rempli d'un adhésif conducteur. L'application de l'électrode de feuille arrière sur la HTL à nanoparticules implique un processus d'application humide, où une encre adhésive conductrice est appliquée, tandis que la feuille arrière conductrice repose sur la HTL, d'une manière telle que l'encre sèche complètement tandis que la feuille est appliquée sur la surface. L'encre adhésive comprend un solvant, un liant, une nanoparticule de carbone conductrice en tant que charge, des nanoparticules semi-conductrices telles que l'oxyde métallique ou la chalcopyrite pour un transfert de charge efficace, et des agents de modification en tant qu'additifs pour ajouter des propriétés supplémentaires à l'encre.
