Abstract
(EN) The purpose of the present invention is to provide a solar cell capable of exhibiting high photoelectric conversion efficiency even after having passed through a heating step. The present invention is a solar cell having, in the stated order, a negative electrode, a photoelectric conversion layer, a hole transport layer, and a positive electrode. The photoelectric conversion layer contains an organic-inorganic perovskite compound represented by AMX (where A is an organic base compound and/or alkaline metal, M is a lead or tin atom, and X is a halogen atom). The hole transport layer contains a halogenated quaternary amine salt.
(FR) Le but de la présente invention est de fournir une cellule solaire pouvant présenter une efficacité de conversion photoélectrique élevée même après avoir traversé une étape de chauffage. La présente invention est une cellule solaire comportant, dans l'ordre indiqué, une électrode négative, une couche de conversion photoélectrique, une couche de transport de trous et une électrode positive. La couche de conversion photoélectrique contient un composé de pérovskite organique-inorganique représenté par AMX (où A est un composé de base organique et/ou un métal alcalin, M est un atome de plomb ou d'étain, et X est un atome d'halogène). La couche de transport de trous contient un sel d'amine quaternaire halogéné.
(JA) 本発明は、加熱工程を経た場合であっても高い光電変換効率を発揮できる太陽電池を提供することを目的とする。本発明は、陰極、光電変換層、ホール輸送層及び陽極をこの順番に有し、前記光電変換層はAMX(但し、Aは有機塩基化合物及び/又はアルカリ金属、Mは鉛又はスズ原子、Xはハロゲン原子である。)で表される有機無機ペロブスカイト化合物を含有し、前記ホール輸送層はハロゲン化4級アミン塩を含有する太陽電池である。
