Title: Achieving 20% Efficiency for Inverted Perovskite Solar Cells by Using Low-Temperature Solution-Processed TFB as Hole-Transporting Layer

Abstract: Low-temperature-processed inverted perovskite solar cells (PVSCs) attract increasing attention because they can be fabricated on both rigid and flexible substrates. For this devices, hole-transporting layers (HTLs) play an important role in achieving efficient and stable inverted PVSCs by adjusting the anodic work function, hole extraction, and interfacial charge recombination. Here, we report the use of a low-temperature (≤ 150 °C) solution-processed ultrathin film of poly[(9,9-dioctyl-fluorenyl-2,7-diyl)-co-(4,4′-(N- (4-secbutylphenyl) diphenylamine)] (TFB) as an HTL in one-step-processed CH3NH3PbI3 (MAPbI3)-based inverted PVSCs. The fabricated device exhibits power conversion efficiency (PCE) as high as 20.2% when measured under AM 1.5 G illumination. This PCE makes them one of the MAPbI3-based inverted PVSCs that have the highest efficiency reported to date. Moreover, this inverted PVSC also shows good stability, which can retain 90% of its original efficiency after 30 days of storage in ambient air.
