The development of hole-collecting materials is indispensable to improving the performance perovskite solar cells (PSCs). To date, several anchorable molecules have been reported as effective monolayer (HCM) for p–i–n PSCs. However, their structures are limited well-known electron-donating skeletons, such carbazole, triarylamine, etc. In this work, we developed a series squaraine derivatives that π-conjugated core composed squaric acid moiety connected an indoline moiety. Thanks polar carbonyl group acid, all were found form hydrophilic monolayers after being chemisorbed on transparent conducting oxide surfaces, which beneficial subsequent deposition layer. effect substituents and anchoring groups molecular electronic structure well cell device's was elucidated. PSC devices fabricated by using these exhibited high power conversion efficiencies up 22.1%, together with good stability. This work highlights potential simple skeleton building block realize high-efficiency cost-effective
