    The widespread application of self-assembled monolayer (SAM) hole transport materials has driven rapid advancements in the performance of inverted perovskite solar cells (PSCs). However, the difficulty of achieving a highly ordered SAM for hole transport and the weak binding strength between SAM and the perovskite layer not only leads to defective bottom interface but also reduces the compatibility with the large-area device fabrication. In this work, a co-assembled molecule functionalized with a diamide terminal group is demonstrated that is able to form supramolecular interaction with popular carbazole-based SAMs for regulating their structural ordering, and to improve the chemical bonding with perovskite Pb-I frameworks synergistically, which enables efficient and long-term stable inverted PSCs. As a result, the target co-assembled SAM contributes to a champion small-area device with a power conversion efficiency (PCE) of 25.3% (certified 25.0%), and demonstrates good compatibility with large-area fabrication by achieving highly reproducible performances in 1.02 cm<sup>2</sup> devices. The encapsulated devices exhibit good stability with 92.8% and 91.2% of initial PCE after 1500 hours of aging under 85 °C and maximum power point (MPP) tracking at 65 °C for 1500 hours, respectively.

    <jats:title>Abstract</jats:title><jats:p>Exploiting the self‐assembled molecules (SAMs) as hole‐selective contacts has been an effective strategy to improve the efficiency and long‐term stability of perovskite solar cells (PSCs). Currently, research works are focusing on constructing SAMs on metal oxide surfaces in <jats:italic>p‐i‐n</jats:italic> PSCs, but realizing a stable and dense SAM contact on halide perovskite surfaces in <jats:italic>n‐i‐p</jats:italic> PSCs is still challenging. In this work, the hole‐selective molecule for <jats:italic>n‐i‐p</jats:italic> device is developed featuring a terephthalic methylammonium core structure that possesses double‐site anchoring ability and a matching diameter (6.36 Å) with the lattice constant of formamidinium lead iodide (FAPbI<jats:sub>3</jats:sub>) perovskite (6.33 Å), which facilitates an ordered and full‐coverage SAM atop FAPbI<jats:sub>3</jats:sub> perovskite. Moreover, theoretical calculations and experimental results indicate that compared to the frequently used acid or ester anchoring groups, this ionic anchoring group with a dipolar charge distribution has much larger adsorption energy on both organic halide terminated and lead halide terminated surfaces, resulting in synergistic improvement of carrier extraction and defect passivation ability. Benefiting from these merits, the efficiency of PSCs is increased from 21.68% to 24.22%. The long‐term operational stability under white LED illumination (100 mW cm<jats:sup>−2</jats:sup>) and at a high temperature of 85 °C is also much improved.</jats:p>

    Organic molecule passivation of perovskite surfaces has emerged as a promising strategy for efficient and durable perovskite solar cells (PSCs). While many materials have been reported, the optimization of molecular structure for the best passivation effect remains of significant interest but lacks sufficient study. In this work, we designed and synthesized three novel donor–acceptor-donor (D-A-D) type conjugated organic small molecules with varying alkyl chain lengths to regulate the interface between perovskite and Spiro-OMeTAD. Among them, the OSIT molecule, which features an n-octyl side chain of optimal length, demonstrated a balanced interfacial contact and interaction with the perovskite surface. Beyond the passivation effect of the electron-rich C=O group on undercoordinated Pb<sup>2+</sup> defects, OSIT optimizes energy level alignment and improves charge extraction by acting as an efficient hole transport channel. As a result, PSCs with OSIT interfacial layer achieved an exceptional efficiency of 25.48% and a high open-circuit voltage of 1.18 V. Furthermore, the durability of unencapsulated devices was significantly enhanced under various environmental conditions, maintaining 93.7% of their initial efficiency after 1000 h of maximum power point tracking in a nitrogen atmosphere. This study provides valuable insights into the rational design of D-A-D type materials for effective interface modification in PSCs.

    Spiro-OMeTAD is a widely used hole transport material (HTM) in perovskite solar cells (PSCs), but its inherent low hole mobility and poor thermal stability affect the overall performance of PSCs. To overcome these limitations, we develop a series of fluorene-terminated Spiro-type HTMs, engineered by modulating the fluorene substitution site and π-conjugated intensity. Among these, the p-BM material exhibits high energetic ordering in film, appropriate energy levels, and efficient carrier extraction, enabling PSCs to achieve power conversion efficiencies (PCEs) of 25.5% and 24.03% for aperture areas of 0.0625 and 1 cm<sup>2</sup>, respectively. Additionally, a perovskite solar mini-module (size 16 cm<sup>2</sup>) based on p-BM HTM achieved a PCE of 22.4%. More importantly, p-BM exhibits a high glass transition temperature and enhanced film hydrophobicity, significantly improving the stability of devices in relation to heat and humidity. Our findings provide a promising alternative HTM for developing efficient and stable perovskite photovoltaic devices.

    The electron affinity (EA) and ionization energy (IE) of battery electrolyte molecules are pivotal in determining the electrochemical properties of electrode materials, significantly impacting the performance and safety of batteries. In this study, we employed a suite of machine learning algorithms, including linear regression, gradient boosting, CatBoost, XGBoost, and random forest regression, to predict these properties. Our analysis leveraged a comprehensive dataset of 24432 electrolyte molecules extracted from the Joint Center for Energy Storage Research (JCESR) Molecules database, and used RDKit and Mordred tools to generate a series of molecular descriptors. Through meticulous feature engineering and selection using the maximum relevance minimum redundancy (mRMR) algorithm, we identified the most influential molecular features for predicting EA and IE. The CatBoost model emerged as the most accurate, outperforming other models with its ability to handle complex nonlinear relationships and provide robust predictions with lower errors. The model's predictions were further validated through 10-fold cross-validation, demonstrating its generalization capability and resistance to overfitting. The CatBoost model achieved a root mean squared error (RMSE) of 0.239 eV for IE and 0.427 eV for EA, with R-squared (R<sup>2</sup>) values of 0.944 and 0.879, respectively. SHapley Additive exPlanations (SHAP) value analysis elucidated the contribution of each feature to the model's predictions, highlighting the molecular characteristics that significantly influence EA and IE. Our findings offer valuable insights for the design of novel electrolyte materials with tailored electronic properties, advancing the development of high-performance battery technologies.

    　More details

    To further enhance the performance of perovskite solar cells (PSCs), a more comprehensive analysis of the mechanisms through which organic molecules induce defect passivation and enhance hole extraction is essential. In this study, we employ several organic molecules with varying π-conjugation lengths to examine how factors such as their molecular desorption, energy levels, and radical-cation stability affect defect passivation, hole extraction, and the overall PSC performance. Our results show that passivation molecules with extended π-conjugation suppress molecular desorption from the perovskite surfaces during overlayer spin-coating and improve energy-level alignment at interfaces, thereby enhancing PSC efficiency through improved defect passivation and hole extraction. Additionally, extended π-conjugation improves radical-cation stability, contributing to greater device durability. Among the defect passivation materials studied, 2-(3-ethylamine)benzothieno[3,2-b]benzothiophene hydroiodide (BTBTAI) can provide the most significant improvements in these factors, increasing the initial efficiency from 22.7% to 24.6% and raising the efficiency retention from 61% to 85% after 1000 hours of continuous light illumination at 25 °C in formamidinium lead iodide-based PSCs. Reports on defect passivation from the perspectives of molecular desorption and cation stability are extremely limited. Therefore, these findings deepen the understanding of PSC operating mechanisms and offer valuable insights for developing design guidelines for future defect passivation materials with even higher device performance.

    The buried interface in perovskite solar cells (PSCs) is pivotal in influencing the quality of the perovskite films and the efficiency of charge extraction and transport. Recent studies have highlighted the potential of alkali metal ion-based materials for modifying this interface. In this work, we present the first systematic investigation of the effects of different alkali metal hydroxide treatments at the buried interface between the SnO<inf>2</inf> electron transport layer and the perovskite light absorber layer. Our findings demonstrate that KOH treatment significantly enhances the power conversion efficiency (PCE), while CsOH treatment improves operational durability. To achieve a balance between efficiency and durability, we developed a dual alkali metal hydroxide treatment strategy. Notably, the sequence of hydroxide deposition was found to be critical. A KOH treatment followed by CsOH increased the efficiency of mixed cation-based PSCs from 18.46% to 20.31% and improved durability, allowing the device to retain 95% of its initial efficiency after 500 h of continuous illumination at room temperature. Furthermore, this dual treatment enhanced the PCE of formamidinium lead iodide-based PSCs from 21.31% to 21.68%, along with improved operational stability. This study introduces a straightforward yet highly effective method for buried interface modification, offering a versatile approach to simultaneously boost efficiency and durability in a wide range of PSC architectures.

    Perovskite materials have attracted significant attention due to their applications in solar cells. Direct bandgap perovskite materials are renowned for their high efficiency, tunability, and low cost in the field of optoelectronics. This study delves into the prediction and analysis of the bandgap properties of perovskite materials through machine learning techniques, aiming to provide a scientific basis for the design and optimization of these materials. By meticulously curating and preparing the dataset from the Materials Project database, we ensured a high-quality foundation for model training. We employed innovative feature engineering methods to gain a profound understanding of the relationship between material structure and properties. Various machine learning algorithms were utilized to compare the predictive performance of different models. Notably, the CatBoost model demonstrated the highest AUC value of 0.844(95 %CI:0.816–0.870) without considering thermodynamic stability, showcasing its superior classification performance. In the second phase, where stability was taken into account, the Gradient Boosting model achieved an AUC value of 0.864(95 %CI:0.806–0.917), indicating that stability significantly impacts the formation of perovskite bandgap properties. Furthermore, the application of SHAP and LIME methods provided interpretability to our model predictions, revealing the crucial factors that influence the bandgap properties of perovskite materials.

    The SnO<inf>2</inf> electron transport layer (ETL), fabricated by spin-coating from commercially available aqueous colloidal dispersion, is widely used in perovskite solar cells (PSCs). In this study, we demonstrate that the relative humidity (RH) during SnO<inf>2</inf> spin-coating significantly affects PSC performance. Spin-coating at higher RH levels leads to the formation of rougher SnO<inf>2</inf> ETL surfaces with numerous pinholes, which results in reduced PSC performance due to partial contact between the perovskite light absorber and the indium tin oxide (ITO) electrode layer. In contrast, smoother, pinhole-free SnO<inf>2</inf> ETL surfaces are achieved by spin-coating at lower RH levels, reducing ITO/perovskite contact and thereby enhancing PSC performance. A double-layer SnO<inf>2</inf> architecture is proposed to further improve PSC performance. In this architecture, the first SnO<inf>2</inf> layer, fabricated at 0% RH with a smooth surface, minimizes direct ITO/perovskite contact, while the second SnO<inf>2</inf> layer, fabricated at 80% RH with a rougher surface, enhances electron extraction by increasing the SnO<inf>2</inf>/perovskite interface area. These findings underscore the importance of controlling RH during SnO<inf>2</inf> spin-coating to achieve PSCs with better reproducibility.

    Perovskite materials have exhibited promising potential in various fields, including solar cells, photodetectors, and light-emitting devices, owing to their exceptional optoelectronic properties and low-cost synthesis methods. In this work, the quest for thermodynamic stability in perovskite materials for optoelectronic applications is addressed through a machine learning (ML) approach. We also analyzed the importance of cations in the stability of double perovskites. It was found that the AUC (area under the curve) and accuracy of the LightGBM model in classification are 0.918 and 0.92, respectively, and the RMSE (root mean square error) and R<sup>2</sup>-score in regression are 0.119 and 0.872, respectively. Subsequently, the model was used to predict the properties of 10 new perovskites with high accuracy. Finally, the analysis of cationic sites revealed that the stability of the double perovskite is significantly affected by the elements occupying the A, B, and B’ sites. Our results provide an optimal machine learning approach for discerning the thermodynamic stability of double perovskites, which can be a useful guide for tuning the properties of perovskite materials.

    Inverted positive-intrinsic-negative (p-i-n) perovskite solar cells (IPSCs) have attracted widespread attention due to their low fabrication temperature, good stability in ambient air, and the potential for use in flexible and tandem devices. In recent years, self-assembled monolayers (SAMs) have been investigated as a promising hole-selective contact for IPSCs, leading to an impressive record efficiency of about 26%, which is comparable to that of the regular n-i-p counterparts. This review focuses on the progress of SAM-based IPSCs from the perspective of energy level matching, defect passivation, interface carrier extraction, and SAMs’ stability improvement, as well as the advances in up-scalable fabrication of SAMs and perovskite layers for efficient solar modules and tandem devices. A cost analysis of the SAMs and other commonly used hole-selective materials is conducted to evaluate their cost-effectiveness for photovoltaic applications. Finally, the future challenges are pointed out and the perspectives on how to up-scale SAM-based IPSCs and improve their long-term operational stability are provided.

    Although perovskite solar cells (PSCs) have attracted significant attention due to their outstanding performance, the optimization of PSC fabrication remains challenging, requiring tremendous amounts of experiments because of the diversity in perovskite compositions and the different concentrations of charge transport layers. Herein, we introduced methodologies to effectively reduce the fabrication time of PSCs. We focused on each step: substrate washing, electron transport layer coating, and perovskite layer coating. Through these steps, we could successfully reduce the overall fabrication time to 49.2% of its previous duration. Furthermore, this method significantly reduces the defect rate from 18.6% to 6.3%, thereby improving the reproducibility and performance of PSCs simultaneously.
