摘要
Perovskite solar cells have received considerable attention for their increasing photovoltaic performance achieved through fine optimization of stacking layers and experimentation with device architecture. The incorporation of interlayers has been shown to positively impact the fabrication process by improving photovoltaic parameters. In recent years, carbazole‐based Self‐Assembled Monolayers (SAMs) have been investigated as a potential Hole Transport Layer (HTL), due to their efficient passivating nature at the hole selective interface and faster charge extraction. This study introduces a novel interlayer2‐decyl[1]benzothieno [3,2‐ b ][1]benzothiophene (C10‐BTBT), over the HTL self‐assembled monolayer (2‐(3,6‐Dimethoxy‐9H‐carbazol‐9‐yl) ethyl) phosphonic acid, also known as MeO‐2PACz. This new interlayer over SAMs significantly improves charge transfer at the interface, resulting in a high fill factor of 85.89% and a boost in power conversion efficiency from 18.04% to 20.50%. This research highlights the potential of interlayer‐SAM combinations in advancing perovskite solar cell technology. This article is protected by copyright. All rights reserved.
