摘要：In printable carbon-based perovskite solar cells (p-MPSCs) utilizing a mesoporous TiO2/ZrO2/carbon architecture optimized for large-scale fabrication, power conversion efficiency (PCE) is limited by suboptimal perovskite crystallization due to drop-casting and the absence of a hole-transporting layer, both of which hinder efficient charge transport and extraction. Herein, an innovative dual strategy combining seed-induced crystallization and interface energy level engineering is introduced to enhance p-MPSC performance. Specifically, CsPbBr3 seeds embedded within the mesoscopic TiO2 electron transport layer promote large-grain perovskite growth, while a screen-printed SnS quantum dot (QD) layer on mesoporous ZrO2 forms a type-II SnS QD/perovskite heterojunction. This approach effectively suppresses grain boundary recombination and optimizes band alignment, reducing energy barriers and enhancing carrier dynamics at the perovskite/carbon interface. The resulting p-MPSC achieves an impressive PCE of 20.8% and an open-circuit voltage (V OC) of 1.067 V, the highest V OC reported for organic-inorganic hybrid p-MPSCs to date. Additionally, a large-area module (17.88 cm2) delivers a remarkable PCE of 17.1% with excellent long-term operational stability. This work presents a robust strategy for simultaneously optimizing crystallization and hole extraction, paving the way for high-efficiency, scalable p-MPSCs.
