Universal in situ oxide-based ABX-structured seeds for templating halide perovskite growth in All-perovskite tandems.

Precise control over halide perovskite crystallization is pivotal for realizing efficient solar cells. Here, we introduce a strategy utilizing in-situ-formed oxide-based ABX-structured seeds to regulate perovskite crystallization and growth. Introducing potassium stannate into perovskite precursors triggers a spontaneous reaction with lead iodide, producing potassium iodide and lead stannate.

Light Management in 2D Perovskite Toward High-Performance Optoelectronic Applications.

Two-dimensional Dion-Jacobson (DJ) perovskite has garnered significant attention due to its superior responsivity and operation stability. However, efforts are predominantly focused on discovering new organic spacer to synthesize novel perovskites, while material-form-associated light management, which is crucial for enhancing the photodetector's efficiency, is largely overlooked. Herein, we introduced surface light management strategy into DJ-type perovskite system by synthesizing surface-patterned BDAPbBr (BPB, BDA = NH(CH)NH) microplates (MPs) using template-assisted space-confined method, which was further elucidated by theoretical optical simulation.

Regulation of nucleation and crystallization for blade-coating large-area CsPbBr perovskite light-emitting diodes.

Metal halide perovskite light-emitting diodes (PeLEDs) and large-area perovskite color conversion layers for liquid crystal display exhibit great potential in the field of illumination and display. Blade-coating method stands out as a highly suitable technique for fabricating large-scale films, albeit with challenges such as uneven nucleation coverage and non-uniformity crystallization process. In this work, we developed an in-situ characterization measurement system to monitor the perovskite nucleation, and crystallization process.

The effect of shared ecological value on buyer-supplier relationship within mountaineering tourism.

Shared values play an important role in attracting new tourists, retaining existing ones and gaining an important competitive advantage. Building upon the Commitment-Trust model, this study tested the role of shared ecological values in the creation of tourist trust and relationship commitment, and finally tourist behavioral intention. To test the hypotheses, a sample consisting of 480 mountaineering tourists of two representative travel agencies were surveyed, and a mixed-method approach based on a quantitative survey (n = 436) and qualitative interviews (n = 60) was also adopted to examine their relationships.

Buried interface modification and light outcoupling strategy for efficient blue perovskite light-emitting diodes.

Perovskite light-emitting diodes (PeLEDs) exhibit remarkable potential in the field of displays and solid-state lighting. However, blue PeLEDs, a key element for practical applications, still lag behind their green and red counterparts, due to a combination of strong nonradiative recombination losses and unoptimized device structures. In this report, we propose a buried interface modification strategy to address these challenges by focusing on the bottom-hole transport layer (HTL) of the PeLEDs.

Intermediate Phase Suppression with Long Chain Diammonium Alkane for High Performance Wide-Bandgap and Tandem Perovskite Solar Cells.

Wide bandgap (WBG) perovskite can construct tandem cells with narrow bandgap solar cells by adjusting the band gap to overcome the Shockley-Queisser limitation of single junction perovskite solar cells (PSCs). However, WBG perovskites still suffer from severe nonradiative carrier recombination and large open-circuit voltage loss. Here, this work uses an in situ photoluminescence (PL) measurement to monitor the intermediate phase evolution and crystallization process via blade coating.

A Multifunctional Additive Strategy Enables Efficient Pure-Blue Perovskite Light-Emitting Diodes.

Lead halide perovskites have shown exceptional performance in light-emitting devices (PeLEDs), particularly in producing significant electroluminescence in sky-blue to near-infrared wavelengths. However, PeLEDs emitting pure-blue light at 465-475 nm are still not satisfactory. Herein, efficient and stable pure-blue PeLEDs are reported by controlling phase distribution, passivation of defects, as well as surface modifications using multifunctional phenylethylammonium trifluoroacetate (PEATFA) in reduced-dimensional p-F-PEA Cs Pb (Br Cl ) polycrystalline perovskite films.

A generic lanthanum doping strategy enabling efficient lead halide perovskite luminescence for backlights.

Metal halide perovskites films have attracted great interest because of their solution-proceed fabrication and potential applications for next-generation displays. However, their non-ideal photoluminescence quantum efficiency (PLQE) and stability still does not meet the requirements of displays. Here, we adopt lanthanum ion (La) doping strategy to enhance its luminescence performance and the possibility of taking it to commercialization.

With a case study from Chengdu-Chongqing Economic Circle of China, this paper attempts to empirically justify the framework. An index system was established for evaluating CKMC based on BSC and knowledge management process, the weight design and consistency check of the indexes were implemented by using the analytic hierarchy process (AHP), and the overall evaluation value and concrete index scores at all levels were obtained via the fuzzy evaluation method.

Do urban tourists prefer vegetarianism? An urban-rural comparison of vegetarian consumption in China.

The adoption of a vegetarian diet might have public health and environmental benefits. However, little is known about urban and rural Generation Z tourists' attitudes toward vegetarianism or vegetarian consumption within the Chinese urban and rural settings. Hence, to address this gap, the present study adopted a sequential and mixed research approach based on a survey ( = 212) and laddering interviews ( = 20) to validate post-millennial tourists' motives for adopting a vegetarian diet.

Environmental safety evaluation of geopark based on CPTED concept and fuzzy comprehensive analysis.

In recent years, with the increasingly popular and openness of Geoparks, Environmental safety has become a major concern for sustainable geo-tourism. It is therefore necessary to conduct an environmental safety performance evaluation for promoting geo-tourism development. In order to identify and figure out the factors influencing the tourists' environmental safety perception, an index system was established based on six principles of Crime Prevention Through environment design (CPTED) theory.

Influence of Interpersonal and Institutional Trust on the Participation Willingness of Farmers in E-Commerce Poverty Alleviation.

To explore the influence of interpersonal trust and institutional trust on the participation willingness of farmers in e-commerce poverty alleviation in China, a questionnaire survey of 320 farmers in Chongqing Ecological Tourism District was adopted for data collection, and a binary logistic model was used for data analysis. The results showed that (1) both interpersonal trust and institutional trust had a positive influence on the participation behavior of farmers in e-commerce poverty alleviation, and the priority ranking from high to low was: trust in government, trust in relatives, trust in neighbors, and trust in village cadres. (2) Institutional trust had a greater impact on the participation behavior of farmers than interpersonal trust, especially in the poverty-stricken areas where economic development was relatively backward.
