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 ：
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 ：
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 ：
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 ：
反式钙钛矿太阳能电池（PSCs）是迄今报道的最有效的器件类型之一。然而，PSCs存在的非辐射复合损耗显著以及钙钛矿薄膜存在大量的缺陷限制了这些器件的重复性和性能，因此迫切需要一种有效的方法来最小化PSCs在钙钛矿层的陷阱密度。本研究将甲基碘化铵（MAI)作为界面钝化层同时对空穴传输层（HTL）以及钙钛矿活性层上层进行缺陷钝化。研究表明，MAI界面钝化层通过钝化钙钛矿表面和底部以及钙钛矿活性层的晶界，实现了效率的双重提升。采用综合钝化策略的未封装PSCs达到了最高的光电转换率（PCE）为22.70%。

Abstract ：
The interfacial modification is crucial for achieving high efficiency and stability in perovskite solar cells (PSCs). Here, we have developed a concise and efficient dual-interface passivation strategy by incorporating mixed cations of phenylethylammonium iodide and methylammonium iodide (PEAI and MAI, denoted as PMI) at both the interfaces of the electron and hole transport layers (HTL). The buried interface enhances HTL wettability and improves perovskite crystallinity, thereby enhancing its performance. Simultaneously, modifying the top surface of the perovskite effectively reduces defects and nonradiative recombination losses. As a result, inverted PSCs exhibit improved V-OC, J(SC), and FF, leading to a peak PCE of 24.20 %. Compared to the control device (PCEmax = 21.78 %), there is an similar to 11.11 % enhancement in PCE. Importantly, the passivated PMI-based devices demonstrate exceptional stability even under harsh conditions of 60 degrees C and 35 % RH. After 1440 h, their PCE retains an impressive 75.3 % of the initial performance, showcasing a remarkable improvement of 21.2 % compared to the control devices (62.1 %). The observed stability exceeds previous studies on PTAA-based inverted PSCs.

Abstract ：
Perovskite solar cells(PSCs)have been demonstrated to be one of the most promising technologies in the field of renewable energy.However,the presence of the defects in the perovskite films greatly limits the efficiency and the stability of the PSCs.The additive engineering is one of the most effective approaches to overcome this problem.Most of the successful additives are extracted from the petroleum-based materials,while the research on the biomass-based additives is still lagging behind.In this paper,two ecofriendly hydroxyalkyl cellulose additives,i.e.,hydroxyethyl cellulose(HEC)and hydroxylpropyl cellulose(HPC),are investigated on the performance of the MAPbl3-based inverted PSCs.Due to the strong interaction between the hydroxyl groups of the cellulose and the divalent cations of the perovskite,these additives enhance the crystal grain orientation and significantly repair the defects of the perovskite films.Working as the additives,these two cellulose derivatives show a strong passivation ability,which significantly reduces the trap density and improves the optoelectronic feature of the PSCs.Compared with the average power conversion efficiency(PCE)of the control device(19.19％),an enhancement of～10％is achieved after the addition of HEC.The optimized device(PCE=21.25％)with a long-term stability(10:80 h,PCE=20.93％)is achieved by the incorporation of the HEC additives into the precursor solution.It is the best performance among the PSCs with the cellulose additives up to now.This research provides a novel choice to develop a cost-effective and renewable additive for the PSCs with high efficiency and excellent long-term stability.

Abstract ：
Excited-state intramolecular proton transfer (ESIPT) materials have attracted much interest, attributed to their metastable excited states which provide suitable platforms for efficient intersystem crossing (ISC) and reverse intersystem crossing (rISC). However, the studies on the utilization of ESIPT to achieve effective hybridized local/charge transfer (HLCT) emitters are rarely reported, due to their ubiquitous issue of low photo-luminescence quantum yields (OPLs). In this research, a novel ESIPT molecule with HLCT characteristic, 4 '- (diphenylamino)-4-(1,4,5- triphenyl-1H-imidazol-2-yl)-[1,1 '-biphenyl]-3-ol(HIT-TPA), is designed and synthe-sized. The hydrogen atom in this molecule can transfer on the way of an intramolecular hydrogen bond from a proton-donating part (-OH/-NH-) to the accepting one (C--O/C--N-). The HLCT and /or color-tuned fluores-cence are observed by the irradiation of specific wavelength, which followed the guidance of ESIPT. It is consistent with the results of transient absorption and time-resolved photoluminescent spectroscopy. By the synergistic interaction of ESIPT and HLCT, the film based on the target molecule presents a high OPL value of-75.5%. After employing HIT-TPA as the emitter for doped/undoped organic light-emitting diodes (OLEDs), a maximum external quantum efficiency of-10.08% is achieved, which proves the efficient triplet harvesting in the ESIPT-based HLCT material. Noticeably, the device exhibits a violet-blue emission with the CIE(x,y) of (0.152, 0.051). It is among the highest reported EQE values on the ESIPT-HLCT materials for violet-blue devices. These results not only open a novel pathway to design effective ESIPT attributed HLCT materials, but also provide a strategy to efficiently utilize ESIPT emitters in achieving high-performance OLEDs.
