AB  - The spontaneous formation of self-assembly monolayer (SAM) on various substrates 
      represents an effective strategy for interfacial engineering of optoelectronic 
      devices. Hole-selective SAM is becoming popular among high-performance inverted 
      perovskite solar cells (PSCs), but the presence of strong acidic anchors (such as 
      -PO(3)H(2)) in state-of-the-art SAM is detrimental to device stability. Herein, 
      we report for the first time that acidity-weakened boric acid can function as an 
      alternative anchor to construct efficient SAM-based hole-selective contact (HSC) 
      for PSCs. Theoretical calculations reveal that boric acid spontaneously 
      chemisorbs onto indium tin oxide (ITO) surface with oxygen vacancies facilitating 
      the adsorption progress. Spectroscopy and electrical measurements indicate that 
      boric acid anchor significantly mitigates ITO corrosion. The excess boric acid 
      containing molecules improves perovskite deposition and results in a coherent and 
      well-passivated bottom interface, which boosts the fill factor (FF) performance 
      for a variety of perovskite compositions. The optimal boric acid-anchoring HSC 
      (MTPA-BA) can achieve power conversion efficiency close to 23% with a high FF of 
      85.2%. More importantly, the devices show improved stability: 90% of their 
      initial efficiency is retained after 2400 h of storage (ISOS-D-1) or 400 h of 
      operation (ISOS-L-1), which are 5-fold higher than those of phosphonic acid 
      SAM-based devices. Acidity-weakened boric acid SAMs, which are friendly to ITO, 
      exhibits well the great potential to improve the stability of the interface as 
      well as the device.
