Abstract
Self-assembled monolayers (SAMs) have received increasing interest in the application of perovskite photovoltaics (PV). However, the deposition of SAMs in most of the studies rely on spin-coating, which is impractical for upscaling applications. In this work, the dip-coating deposition of SAMs is studied for application in p-i-n structured perovskite solar cells. It is found that the dip-coating can not only replace spin-coating in device fabrication but also provide improved uniformity and density of the SAM compared to spin-coating, which leads to enhanced charge extraction with reduced interface defects. Consequently, the perovskite solar cells prepared with the dip-coated SAM demonstrates an improved power conversion efficiency of 23.5%, providing a new pathway for the commercialization of SAMs-based perovskite.
