To overcome this problem, we developed a stable inorganic copper-based chalcogenide (CuxS, x = 1.75) that can cooperate with spiro to serve as the HTL for planar n-i-p PVSCs. The CuxS HTL has two main functions: 1) enhancing hole transport due to its high intrinsic mobility and proper energy level alignment, resulting in a better charge transfer and reduced charge recombination; 2) protecting the spiro layer from damage from both moisture and the top Au anode, through the formation of a physical hydrophobic buffer layer. PVSCs with enhanced power conversion efficiencies (PCEs) are realized through this simple approach, yielding the highest PCE of 18.58% and a steady-state PCE of 17.91%. Furthermore, benefiting from the hydrophobic nature of CuxS, PVSCs retained over 90% of their initial efficiency, even after storage in air with approximately 40% humidity for 1000 h without encapsulation. This study demonstrates that CuxS is a potential hole transport material for fabricating low-cost and efficient PVSCs with long-term stability.
