| Résumé : |
L'objectif principal de ce travail est d'étudier l'effet du matériau CuSCN sur les
cellules solaires à pérovskite, on utilisant le logiciel de simulation SILVACO. Nous avons présenté une partie théorique qui contient des concepts de base sur les cellules solaires à pérovskite en général. La simulation nous a permis d'étudier l'effet du matériau PEDOT : PSS sur la propriété électrique (I-V). Nous avons étudié l'effet du remplacement de PEDOT: PSS par le matériau CuSCN, cette étude a prouvé que le matériau CuSCN améliorait les paramètres de sortie des cellules solaires en pérovskite, après cela, nous avons étudié l'effet de la concentration de dopage de la couche CuScN sur les propriétés électriques des cellules solaires, un résultat important obtenu également de cette étude est la concentration de dopage de la couche de CuScN qui a amélioré la propriété électrique (IV) et les propriétés électriques de la cellule solaire pérovskite. Mot clé : Perovskite, MAPbI3, Silvaco, HTL, CuSCN |
