Abstract Hole transport materials (HTMs) play a crucial role in realizing efficient perovskite solar cells (PSCs), as they improve affinity and passivation, charge extraction, ultimately the performance of PSCs. In this study, manipulating conjugation extension poly(triaryl amine) (PTAA) derivatives by cyclic alkoxylation side benzene groups with benzo[ d ][1,3]dioxole (PTAAO5) dihydrobenzo[ b ][1,4]dioxine (PTAAO6) is focused on. PTAAO6 exhibits extended π‐conjugation within groups, leading to improved energy level alignment enhanced carrier compared both PTAA PTAAO5. This strong also promotes interactions between perovskite, resulting larger grain sizes reduced defects layer. Therefore, PSCs incorporating HTM achieve an outstanding power conversion efficiency 25.19%, along excellent operational stability, retaining 90.2% initial PCE after 1000 h under ISOS‐L‐3 testing conditions.

However, the agglomeration of SAM and lack defect passivation ability are two critical issues that need to be addressed. It is demonstrated by blending co‐adsorbent 4‐phosphoricbutyl ammonium iodide (4PBAI) with 4‐(7H‐dibenzo[c,g]carbazole‐7‐yl) phosphonic acid (4PADCB), enhanced homogeneity, conductivity, better energy levels can realized for co‐SAM contact. functional group 4PBAI also effectively passivate defects at buried interface template high‐quality growth.

Abstract The dipole moment of hole transport materials (HTMs) plays a vital role in improving the photovoltaic performance inverted perovskite solar cells (PSCs). However, manipulating moments polymer HTMs, which have great operational and bias stability, remains challenging. In this work, HTMs with varying lengths glycol side chains, PTAC‐DEG PTAC‐TEG, are developed. Using random‐walk model extended from chain conformation, (with shorter chains) achieves higher cumulative than PTAC‐TEG. This finding can be attributed to fact that smaller angles enable better alignment, while larger PTAC‐TEG promote aggregation reduces integrated moment. Perovskite films on show enhanced crystallinity lower trap density due improved interfacial charge transport, stronger built‐in electric field, affinity dipole. devices achieve PCE 25.8%, is among highest for PSCs based exhibit outstanding stability under ISOS‐L‐3 (t 95 = 1300 h) ISOS‐D‐3 1200 conditions. study highlights modulation as promising strategy designing efficient, stable cells.
