Abstract ：
Textured Czochralski-grown silicon (CZ-Si) integrated with metal halide perovskites present a promising strategy toward low-cost and high-efficiency tandem photovoltaics due to their superior light-trapping capabilities. The challenges in the perovskite/silicon tandem solar cells (P/S-TSCs) is the hole-selective layers (HSLs) that facilitate efficient charge extraction while preventing interfacial shunting. Self-assembled monolayers (SAMs) often suffer from incomplete coverage and limited reproducibility on textured surfaces. In this study, we present a novel self-assembling molecule, 5-(11H-benzo [a]carbazol-11-yl)isophthalic acid (IPABCz), designed with extended It-conjugation and dual anchoring functionality that demonstrates remarkable texture tolerance on CZ-Si. To fabricate wide-bandgap (similar to 1.68 eV) single-junction perovskite solar cells, devices utilizing IPABCz as the hole transport layer (HTL) achieved a champion power conversion efficiency (PCE) of 21.36 % and exhibited an almost negligible hysteresis of 0.94 %. Notably, the highest PCE recorded for the P/S-TSC based on IPABCz as HSL on textured CZ-Si reached up to 30.56 %. Importantly, both device configurations highlight significant improvements in stability. These findings provide a viable strategy for designing texture-tolerant HSLs that can enhance performance in tandem photovoltaic applications.

Abstract ：
Organic light-emitting diodes (OLEDs) has been attracting much extensive interest owing to their advantages of high-definition and flexible displays. Many advances have been focused on boosting the efficiency and stability. Two innovative dimethylacridine-based emitters, 1,1,2,2-tetrakis(4- (2,7-di-tert-butyl-9,9-dimethylacridin-10(9H)-yl)phenyl ethene (AcTPE), and bis(4-(2,7-di-tert-butyl-9,9-dimethylacridin-10(9H)-yl)phenyl)methanone (Ac2BP) were designed and synthesized, in which TPE-baesed AcTPE presents AIE properties, and with the phenyl as spacer between the DMAC and carbony, aryl-ketone-based Ac2BP doesn't show AIE properties due to the absence of restriction of intramolecular rotations. As the electron-withdrawing ability of carbonyl, well-matched energy levels of the Ac2BP improve carriers transfer and hole injecting process in devices, resulting an efficient green emission with a maximum PE of of 5.64 lm W-1, a EQE of 10.56 % and a maximum CE of 18.27 cd A-1. They are much higher than that of AcTPE-based devices (3.45 cd A-1, 1.18 lm W-1, and 1.46 %). This study provides a promising design strategy for efficient OLED emitters of aryl-ketone-architecture.

Abstract ：
Minimizing the defect density and optimizing surface/interface contacts are crucial for the advancement of high- efficient perovskite solar cells (PSCs). Molecular engineering has been demonstrated to be one of feasible strategies to passivate the defects from bulk, surface, and interface. However, the in-situ passivation the defects from both of the interfaces is hardly reported. Herein, two proof-of-concept molecules, ATR and TTR, were designed and synthesized by constructing asymmetric D-it-A architectures featuring electron-donating 2,7-dimethoxy-9,9dimethyl-acridine or bis(4-methoxyphenyl)amine moiety, an electron-deficient unit of 2-(4-oxo-2-thioxothiazolidin-3-yl) acetic acide and thiophene it-bridge. Both dyes manifested the ability of in-situ passivation the defects from the interfaces. Endowed with distinct passivation features, TTR and ATR exhibited high-quality perovskite films, large grain sizes, and aligned energy levels. The employment of these D-it-A dyes as additives successfully achieved a champion power conversion efficiency (PCE) of 24.69% for TTR and 24.16% for ATR, respectively, which represent the state-of-the-art device performance for thioxothiazolidin-based dyes. Furthermore, the PSC with TTR also showed an exceptional stability. This study offers an effectively molecular design for the passivation strategy to attain high-performance perovskite photovoltaics.

Abstract ：
In the rapidly evolving field of perovskite solar cells (PSCs), addressing defects poses a significant challenge due to their diverse nature and varying patterns based on location. Effective defect control is crucial for achieving high efficiency in PSCs. In this work, a synergistic triad of passivation strategy was proposed, termed the "three-in-one" approach. This method incorporates a multifunctional molecule, PTR, into the PbI2 precursor solution during the two-step fabrication of perovskite film. The carboxyl group (& horbar;COOH) of PTR interacts with SnO2 to rectify oxygen vacancies on its surface, alleviating residual stress at buried interfaces. Due to its large volume, PTR is confined to grain boundaries (GBs) and gradually diffuses towards upper/ buried interfaces. Functional groups such as carbonyl (C & boxH;O), sulfurcarbon (C & boxH;S), and carboxyl (COOH) play key roles in mitigating defects at GBs and both interfaces. Additionally, PTR acts as an interfacial bridging that connects electron and hole transport layers. Consequently, the power conversion efficiency (PCE) of the optimal device (n-i-p configuration) improved significantly from 23.04% (pristine) to 25.77%, with a certified value of 25.44%. The introduction of this triad passivation strategy effectively addresses defects at GBs and both interfaces, paving the way for enhanced performance in PSCs.

Abstract ：
Additive engineering has emerged as the predominant approach for enhancing the performance of perovskite solar cells (PSCs). Donor-pi-acceptor (D-pi-A) dyes with tailored configurations have proven to be a viable and effective strategy for passivating defects and optimizing interfacial contacts. In this study, we present two asymmetrical D-pi-A dyes, designated as TZR and TNR. These dyes are designed and synthesized with identical hole- and electron-transporting backbones but feature distinct pi-bridge groups. They are incorporated into the precursor solution of PbI2 to facilitate in situ passivation of both interfaces and grain boundaries (GBs) during the formation of the perovskite film (two-step process). These dyes effectively penetrate both buried and upper interfaces, allowing for the passivation of defects originating from the GBs, and both interfaces. This significantly reduces defects while enhancing charge transport properties. Notably, the pi-bridge composed of benzo[1,2,5]-thiadiazole in TZR contains unpaired electrons from nitrogen and sulfur atoms. An impressive power conversion efficiency (PCE) of 25.11 % is achieved. This performance significantly surpasses that of TNR-based and pristine devices, achieving PCEs of 24.47 % and 22.88 %, respectively. Furthermore, we observed a significant improvement in the stability of the unencapsulated device, attributed to the exceptional hydrophobicity of the D-pi-A dyes. This study offers valuable insights into achieving high-performance PSCs through careful molecular design.

Abstract ：
The solution-processible perovskite materials, utilizing the existing silicon infrastructure for perovskite/silicon tandem solar cells (P/S-TSCs), have attracted significant interest due to their low-cost and high efficiency. Hole-selective layers (HSLs) are essential for charge extraction and transport in P/S-TSCs. However, conventional HSLs often encounter issues such as poor conductivity, energy level mismatch, and incomplete coverage on textured surfaces. In this regard, a novel fully conjugated biscarboxylate-anchored self-assembled molecule with limited acidity, 5-(9H-dibenzo[a,c]carbazol-9-yl)-isophthalic acid (IPAPhCz), is developed to enhance interaction with the conductive oxide of ITO (Indium tin oxide), which forms a uniform and conformal coverage that significantly improves the crystalline quality of the top perovskite. Additionally, IPAPhCz features a large tilted dipole moment with optimized energy alignment for hole extraction. The resulting 1.68 eV single-junction PSC achieved a champion power conversion efficiency (PCE) of 22.78%, an increase of approximate to 10.37% over devices using 4PACz (PCE = 20.64%). Furthermore, textured P/S-TSCs based on IPAPhCz reached a champion PCE of 31.80% (approximate to 1 cm2), reflecting a approximate to 9.58% enhancement compared to that on 4PACz (PCE = 29.02%). Both devices incorporating IPAPhCz demonstrated improved stability. The findings present a significant methodology for the design of high-performance HSL materials for textured P/S-TSCs.
