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 ：
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 ：
Band gap engineering based on doped two-dimensional (2D) transition metal dichalcogenides (TMDs) has shown great potential in the design and development of new nano photoelectronic devices and their application in photoelectrocatalysis. However, there are two key issues that are difficult to take into account, namely the impurity levels induced by dopant atoms appear in the forbidden band of the doping system, which can become the recombination center of photogenerated carriers, thereby reducing the photocatalytic efficiency. Compared with the carrier mobility of the corresponding doped systems, that of intrinsic 2D TMDs is too low. Understanding the doping mechanism of heteroatoms in these systems and designing corresponding crystal structures rationally is important for solving these problems. In this study, the crystal structures of co-doped monolayer WS2 with Nb and Re atoms were designed using density functional theory, and doping systems with graphene (high carrier mobility) were assembled into a heterostructure using the concept of heterorecombination. The N-P type co-doping of Nb and Re atoms retained the continuous band characteristics of the original monolayer WS2 while also providing the high carrier mobility of graphene, yielding an excellent multipurpose material for manufacturing high-speed Schottky devices and efficient water-splitting H evolution catalysts.

Abstract ：
The buried interface in n-i-p structured perovskite solar cells (PSCs), typically rich in defects, is a critical target for functional molecule passivation strategies to enhance device performance. In this study, three functional molecules bearing different electron-withdrawing groups are investigated to modify the perovskite/electron transport layer (ETL) interface. Remarkably, all three molecules exhibit a dual-anchoring behavior: simultaneously binding to the SnO2 ETL surface using both head and tail functional groups, a binding mode not previously reported. Three passivation molecules bearing distinct electron-withdrawing groups are designed and evaluated: sodium trifluoroacetate (NaTFA), sodium trifluoromethanesulfinate (NaTTSA), and sodium trifluoromethanesulfonate (NaTSA), collectively referred to as NaTXA. Among them, NaTSA containing a sulfonic acid (& horbar;SO3) group, exhibits strongest interfacial binding and most effective passivation, outperforming NaTTSA (& horbar;SO2) and NaTFA (& horbar;COOH). This enhancement is attributed to the stronger electron-withdrawing nature of the & horbar;SO3 group and its favorable energy-level alignment at the buried interface, which minimizes defects at the interface and ensures high-speed carrier transport. As a result, the optimized device achieves a power conversion efficiency (PCE) of 25.60% with substantially improved operational stability. This work provides critical insights into functional group selection for interface engineering and deepens the mechanistic understanding of molecule-mediated passivation strategies in PSCs.

Abstract ：
Perovskite solar cells (PSCs) attract extensive attention due to their excellent photoelectric performance, simple fabrication process, and low cost. However, large-scale manufacturing of PSCs requires processing under air atmosphere. Currently, PSCs with high power conversion efficiency (PCE) are all prepared in inert atmospheres, which significantly increases production costs and makes large-scale production difficult. In recent years, rapid progress is made in the research on preparing highly efficient and stable PSCs in air, paving the way for the industrialization and commercialization of PSCs. At the same time, how to combine these research works with manufacturing processes is also a focus of attention. This article reviews the recent development of PSCs prepared in air atmosphere. Specifically, after summarizing the influence of the surrounding environment on perovskite films, it discusses the strategies for preparing PSCs in air and the development of industrial manufacturing processes, and finally, summarizes the most suitable strategies in various processes and gives future prospects.

Abstract ：
Perovskite solar cells (PSCs) have attracted considerable attention due to their outstanding photovoltaic performance, low manufacturing costs, and extensive application potential. The power conversion efficiency (PCE) of single-junction PSCs has exceeded 27.0%. Polymers are widely employed across various industries owing to their tunable structures and excellent stability. To develop highly efficient and stable PSCs, polymers have been seamlessly integrated into additive strategies, interface engineering materials, and charge transport layers. Among these components, the polymer hole transport layer (HTL) is a focal point of current research. This review comprehensively summarizes the latest advancements in polymer-based HTLs and discusses their regulatory mechanisms, particularly in terms of band arrangement regulation, defect passivation, inhibition of non-radiative recombination, enhancement of wettability, and improvement of stability. Furthermore, the interaction mechanisms between polymers and perovskites are also analyzed. Meanwhile, electron transport layers (ETLs), interface modification layers, and bulk phase passivation additives based on functional polymers are thoroughly explored as well, revealing their mechanisms of action while providing guidance for future developments in polymer-based PSCs. Finally, based on the current state of research and development trends in this field, this review forecasts the future application prospects for polymer materials within PSCs.

Abstract ：
An important challenge in the commercialization of perovskite solar cells (PSCs) is the simultaneous attainment of high power conversion efficiency (PCE) and high stability. Using polymer interfaces in PSCs can enhance durability by blocking water and oxygen and by suppressing ion interdiffusion, but their electronic shielding poses a challenge for efficient and stable PSCs1, 2-3. Here we report a magnetic endohedral metallofullerene Nd@C82-polymer coupling layer, which features ultrafast electron extraction and in situ encapsulation, thereby promoting homogeneous electron extraction and suppressing ion interdiffusion. The Nd@C82-polymer coupling layer in PSCs exhibited a PCE of 26.78% (certified 26.29%) and 23.08% with an aperture area of 0.08 cm2 and 16 cm2 (modules), respectively. The unencapsulated devices retained about 82% of the initial PCE after 2,500 h of continuous 1-sun maximum power point operation at 65 degrees C.

Abstract ：
Inverted flexible perovskite solar cells (f-PSCs) are promising candidates for mechanical photovoltaic applications due to their ease of preparation, lightweight, and portability. However, the weak interface connections, residual strain, and the nonradiative recombination loss among adjacent layers are critical challenges that restrict f-PSCs development. To address these issues, a functionalized molecule with multiple hydrogen bond acceptors, 4-Carboxyphenylboronic acid (4-BBA), is designed in the perovskite precursor for modulating perovskite crystallization, which achieves uniform and stress-relaxation perovskite film and forms a robust bridging structure anchored at the buried interface. Theoretical calculation and experimental results show that the C & boxH;O group passivates Pb2+ with I- vacancy defect through Lewis acid-base interactions, reducing trap-assisted recombination. Furthermore, the designed 4-BBA is preferentially deposited at the buried layer interface between the perovskite and substrate, forming hydrogen bonds with the self-assembled monolayer via B & horbar;OH bonds, creating a mechanically stable bridge between the layers. As a result, the power conversion efficiency of the champion f-PSC reached 25.30% (25.13% certified). And the f-PSC open-circuit voltage set a record of 1.21V. Importantly, the unencapsulated f-PSC using 4-BBA retains 95.3% of its original performance after 5000 cycles at a bending radius of 10mm, demonstrating extraordinary bending stability.

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.
