Self-assembled monolayers (SAMs) have gained significant attention as an interfacial engineering strategy for perovskite solar cells (PSCs) due to their efficient charge transport ability and work function tunability. While solution-based methods such dip-coating spin-coating are widely used SAM deposition, challenges non-uniform coverage, solvent contamination, limited control over molecular orientation hinder scalability reproducibility. In contrast, vacuum deposition techniques, including thermal evaporation, overcome these limitations by enabling the formation of highly uniform materials with precise thickness arrangement. Importantly, chemical interactions between layers, coordination bonding Pb2+ ions, play important role in passivating surface defects, modulating energy levels, promoting crystallization. These not only enhance wettability but also improve overall quality stability films. This review highlights advantages vacuum-deposited SAMs, strong layers improving properties critical scalable applications.

Abstract Self‐assembled molecules (SAMs) have been widely employed as hole transport layers (HTLs) in inverted perovskite solar cells (PSCs). However, the carbazole core of [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic acid (Me‐4PACz) is insufficiently effective for passivating defects at “bottom” films, and weak anchoring ability phosphate groups toward NiO x substrate appears to promote formation dimers, trimers, higher‐order oligomers, resulting molecular accumulation. Herein, a novel technique proposed combine Me‐4PACz with different thiol modify buried interface PSCs. Molecular dynamics simulations infrared scattering‐type scanning near‐field optical microscopy (IR s‐SNOM) results show that co‐depositing forms hybrid SAMs densely uniformly cover surface. The island‐like structure serves template forming bulk heterojunction composed interpenetrating networks MA‐rich FA‐rich domains, enabling efficient charge generation suppressed bimolecular recombination. Particularly, (3‐mercaptopropyl) trimethoxysilane (MPTMS) effectively prevents aggregation by multi‐dentate anchor on surface through hydrolytic condensation ─OCH 3 groups, while its ─SH passivate uncoordinated Pb 2+ perovskite/HTL interface. Consequently, SAMs‐modified PSC achieve champion photoelectric conversion efficiency (PCE) 25.4% demonstrated better operational stability.

Abstract [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl]phosphonic acid (Me‐4PACz) consistently exhibits inhomogeneous distribution on the substrate, which makes it a challenge for growth of high‐quality perovskite film, resulting in undesired interfacial losses at buried interfaces. Moreover, flexible alkyl chains Me‐4PACz are not conducive to intermolecular interactions and hinder charge flow. Here, novel molecule with 4‐Methoxy‐N‐(4‐methoxyphenyl)‐N‐phenylaniline (TPA) carbazole backbone, named CzTPA is designed, constituted Co‐SAM Me‐4PACz.

Abstract Enhancing interfacial adhesion between functional coatings and target surfaces facilitates long‐term stable service by mitigating interferences of mechanical mismatches. Design interlocks affords an effective strategy to strengthen the bonding with durability compatibility, but in‐depth investigations are still lacked. Herein, a gecko‐inspired hierarchical realized hybrid laser direct writing is proposed, which incorporates armored frame scale for surface protection riveted anchor interlocks. Such dual‐scale configurations endow stronger targets than pristine mono‐scale cases, resulting in 2 orders magnitude enhancement resistant tape peeling tests. Utilizing this scheme, laser‐induced integrated deicing system situ manufactured on thermoplastics, primarily comprising superhydrophobic structures, carbon‐based sensors as well adhesive copper (Cu) interconnects heaters, where Cu‐based devices exhibit superior resistance water impacts stress fatigue. Interfacing signal processing modules, such all‐in‐one demonstrates real‐time temperature monitoring high efficiency (4.24 folds faster control group).
