To commercialize perovskite solar cells (PSCs), it is crucial to develop cost‐effective, dopant‐free hole transport layers (HTLs) that can be processed at low temperatures. Herein, a small molecular material 4,4′,4′‐Tris[2‐naphthyl(phenyl)amino]triphenylamine (2TNATA) was utilized in inverted PSCs as HTL. The position of the highest occupied orbital energy 2TNATA properly aligned with valence band maximum. Moreover, lower temperatures and shows excellent thermal stability. lead (Pb) on exhibited superior crystallinity morphology compared poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) poly[bis(4‐phenyl)(2,4,6‐trimethylphenyl)amine] (PTAA). Furthermore, carrier kinetics 2TNATA‐based PTAA PEDOT:PSS‐based PSCs. Consequently, an outstanding power conversion efficiency (PCE) 20.58% observed from HTL‐based 0.09 cm 2 PSCs, while PEDOT:PSS HTLs‐based showed PCE 19.36% 14.35%, respectively. 1.0 demonstrated impressive 20.04%. results indicate might promising HTL for inexpensive efficient
