Summary: Finite 2D/3D hierarchical perovskite structures are constructed using interfacial ligand confinement, resulting in efficient and stable inverted perovskite solar cells (PSCs) and modules. The introduction of a diamine masking reagent regulates cation exchange and forms a finite and dense 2D layer, improving top-contact passivation and electron extraction. The inverted PSCs and modules with finite 2D/3D perovskite layers achieve remarkable power conversion efficiencies of 24.7% and 21.6% (certified PCE of 21.2%), respectively, making them one of the best-performing inverted mini-modules reported so far. Encapsulated PSCs retain over 90% of their original PCE after 1000 hours of illumination. Overall, this work presents an effective approach for further advancing perovskite photovoltaics.

Summary: It is believed that excessive lead iodide (PbI2) has a negative impact on the performance and stability of perovskite solar cells. Moderate PbI2 can improve efficiency by reducing defects, while highly active PbI2 can cause significant hysteresis effects and device instability. Despite efforts to understand the role of excess PbI2, its importance is still underestimated. Recent advances have revealed the potential of modifying excess PbI2, but a comprehensive study is needed for a deeper understanding of its mechanism. This review discusses important breakthroughs and rethinks the efficiency and stability mechanisms of excess PbI2, as well as summarizes the origins, verification, and regulation of residual PbI2.

Summary: Lead-free tin perovskite solar cells (PKSCs) have low efficiency due to rough surface morphology and high number of defects. A posttreatment strategy using sequential passivation with acetylacetone (ACAC) and ethylenediamine (EDA) is proposed to reduce trap density, enlarge grain size, and regulate energy level. The study achieves a promising 13% efficiency with better stability.

Summary: By introducing 1,10-phenanthroline, defects on the surface of polycrystalline perovskite thin films were successfully passivated, and excess/unreacted PbI2 was converted into beneficial complex species, promoting efficient hole transfer at the interface.

Summary: We report the use of a BTBT derivative and a carbazole derivative to improve the interface between sputtered NiOx and halide perovskite in PSCs. Treatment of NiOx with the BTBT derivative significantly enhances the open-circuit voltage (Voc) and boosts the champion power conversion efficiency (PCE). In-depth analysis of the interface reveals that BTBT molecules reside at the bottom interface and successfully suppress a reaction at this interface, leading to improved stability of the PSCs under MPP conditions and in ambient conditions.

Summary: By doping the perovskite precursor with 1,4-butanediamine dihydrochloride (BDACl2), grain growth and defect density reduction are promoted, improving the crystalline quality of the perovskite films and increasing the PSCs device efficiency from 22.47% to 24.12%. Moreover, BDACl2 effectively inhibits the transition from & alpha;-phase to & delta;-phase of FAPbI3, leading to over 80% retained initial PCE of the PSCs after nearly 1500 hours of operation under simulated white light illumination in a nitrogen glove box, while the control cell without BDACl2 modification showed PCE decay of over 58% after the same period of aging.

Summary: Well-functioning domestic institutions play a crucial role in determining the impact of global value chains on the environment. This article empirically assesses the relationship between domestic institutional arrangements and environmental performance index for Asian countries participating in global value chains from 2001 to 2018. The findings suggest that participation in global value chains negatively affects environmental performance index, but this relationship can be reversed when accompanied by governance facilitation.

Summary: By modifying the support of the majority function, we have constructed balanced odd-variable rotation symmetric Boolean functions with optimal algebraic immunity. The nonlinearity of these constructed functions is the highest among all known rotation symmetric Boolean functions with optimal algebraic immunity for n > 17. Simulations also demonstrate that these functions exhibit good fast algebraic immunity for some small numbers of variables.

Summary: The present study examines the relationship, causality, and direction between environmental pollution (CO2), renewable/non-renewable energy, income disparity, exchange rate, and poverty alleviation in E-9 countries of Asia. Using panel data from 1990 to 2018, the study confirms the strong co-integration among these variables. It also finds that non-renewable energy, exchange rate, and income disparity have a uni/bidirectional causality with environmental pollution. The study highlights the negative impact of poverty alleviation, exchange rate, and renewable energy on reducing environmental pollution, while income disparities and non-renewable energy usage contribute to increased pollution. The study emphasizes the need for policies that focus on poverty reduction, decreased non-renewable energy usage, and promoting renewable energy and exchange rate control to address environmental pollution in these developing countries.

Summary: The present work conducted experiments to measure the ignition delay times of hydrogen/n-heptane mixture at high temperature and low pressure using a shock tube. The results showed that mixtures with higher hydrogen proportion and lower equivalence ratio had shorter ignition delay times. As the hydrogen proportion decreased, the inhibition effect of n-heptane on the mixture's ignition weakened. The NUI mechanism was selected for the kinetic study as it was consistent with the experimental values. A skeletal hydrogen/PRF mechanism was updated from a skeletal PRF mechanism based on the shock tube experimental data, and it was validated against various fuel mixtures.

Summary: This study investigates the flame radiation of a rectangular pool fire in longitudinal wind. The results show that the incident heat flux initially increases and then decreases as the air speed increases, with a threshold value at approximately 0.96 m/s. The heat flux is primarily determined by the burning rate at lower air speeds, but is determined by the combination of flame morphology and burning rate at higher air speeds.

Summary: The influence of additional structural elements on the aerodynamic characteristics of a double-slotted box girder for hybrid bridges was investigated. It was found that wind barriers and balustrades have a considerable impact on Vortex-induced vibrations (VIVs), while maintenance rails have limited influence. The distribution of wind pressures on specific parts of the bridge deck further contributed to the generation of torsional VIVs.

Summary: In this article, a novel leader-follower-based particle swarm optimization (LFPSO) algorithm is proposed, which maintains the diversity of the particle population while improving the possibility of escaping from the locally optimal solution. Experimental results demonstrate that the proposed algorithm significantly improves the accuracy and convergence rate of conventional particle swarm optimization algorithms, and its superiority is verified in denoising real-time signals in an oilfield pipeline network.
