This article presents a significant advancement in the stability of perovskite solar cells, which have shown impressive photovoltaic performance but suffer from poor operational stability. The researchers developed a one-year stable perovskite device by engineering a 2D/3D (HOOC(CH2)2NH3)2PbI4/CH3NH3PbI3 perovskite junction, which forms a multi-dimensional interface that enhances stability. The 2D/3D junction yields up to 12.9% efficiency in a carbon-based architecture and 14.6% in standard mesoporous solar cells. To demonstrate the scalability and practicality of their technology, they fabricated 10 × 10 cm² solar modules using a fully printable industrial-scale process, achieving an efficiency of 11.2% and maintaining stability for over 10,000 hours with zero loss in performance under controlled standard conditions. This innovative, stable, and low-cost architecture paves the way for the commercialization of perovskite solar cells.This article presents a significant advancement in the stability of perovskite solar cells, which have shown impressive photovoltaic performance but suffer from poor operational stability.
