摘要： A perovskite solar cell adopts a compound having a specific central backbone having a carbazolylamino group as a substituent, and more particularly, to the perovskite solar cell adopts a compound, as a hole transport material, having a specific central backbone having a carbazolylamino group as a substituent, and a spirobifluorene compound having a carbazolylphenylamino group. The perovskite solar cell has very excellent high-temperature stability while having a high power generation efficiency.
