Protocol for fabricating long-lasting passivated perovskite solar cells

Abstract

Summary: Preparation of perovskite solar cells (PSCs) with long-lasting passivation effectiveness is challenging. Here, we present a protocol for fabricating efficient and stable passivated perovskite solar cells. We describe steps for preparing the electron transporting layer (ETL) via chemical bath deposition and perovskite film. We then detail procedures for passivating the surface defects with excess terpyridine ligands and stability characterization. This protocol features a passivator-terpyridine whose passivation effect is independent of concentration, which greatly improves the durability of the passivation.For complete details on the use and execution of this protocol, please refer to Wang et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
