Low-Cost N,N?-Bicarbazole-Based Dopant-Free Hole-Transporting Materials for Large-Area Perovskite Solar Cells
Despite the recent unprecedented development of efficient dopant-free hole transporting materials (HTMs) for high-performance perovskite solar cells (PSCs) on small-area devices (?0.1 cm2), low-cost dopant-free HTMs for large-area PSCs (?1 cm2) with high power conversion efficiencies (PCEs) have rarely been reported. Herein, two novel HTMs, 3,3?,6,6? (or 2,2?,7,7?)-tetrakis(N,N?-di-p-methoxyphenylamine)-N,N?-bicarbazole (3,6 BCz-OMeTAD or 2,7 BCz-OMeTAD), are synthesized via an extremely simple route from very cheap raw materials. Owing to their excellent film-forming abilities and matching energy levels, 3,6 BCz-OMeTAD and 2,7 BCz-OMeTAD can be successfully employed as a perfect ultrathin (?30 nm) hole transporting layer in large-area PSCs up to 1 cm2. The 3,6 BCz-OMeTAD and 2,7 BCz-OMeTAD based large-area PSCs show highest PCEs up to 17.0% and 17.6%, respectively. More importantly, high performance large-area PSCs based on 2,7 BCz-OMeTAD retain 90% of the initial efficiency after 2000 h storage in an ambient environment without encapsulation.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 52409-22-0, help many people in the next few years.COA of Formula: C51H42O3Pd2
