However, their limited photostability represents a serious obstacle to the commercialization this promising technology. Herein, we present an efficient method for improving intrinsic series commonly used material formulations such as MAPbI3, FAPbI3, Cs0.12FA0.88PbI3, and Cs0.10MA0.15FA0.75PbI3 through modification with octenidine dihydroiodide (OctI2), which is widely antibacterial drug two substituted pyridyl groups cationic centers in its molecular framework. most impressive stabilizing effects were observed case FAPbI3 Cs0.12FA0.88PbI3 absorbers that manifested significant suppression or even blocking undesirable films’ recrystallization other decomposition pathways upon continuous 110 mW/cm2 light exposure. achieved photostability—within 9000 h Oct(FA)n−1PbnI3n+1 (n = 40–400) 20,000 Oct(Cs0.12FA0.88)n−1PbnI3n+1 (where n formulations—matches highest values ever reported complex lead halides.

<p>Lead halide perovskites (LHPs), which have demonstrated exceptional optical and electrical properties are promising candidates for electroluminescent light-emitting diodes (LEDs). However, concerns about the toxicity stability hindered their commercialization. In recent years, lead-free metal (LFMHPs) emerged as alternatives, significant progress has already been made in developing LFMHP-based LEDs. Nevertheless, device performance is still inferior to that of well-developed LHP-based counterparts. To fully exploit LED applications boost performance, this review, we provide a comprehensive overview currently explored different metal-based LFMHPs. We mainly focus on preparation methods, crystal structure, properties, these materials. Furthermore, conclude with discussion regarding key challenges potential prospects field. hope review will inspire more extensive research LFMHPs from new perspective promote practical LEDs multiple directions current future research.</p>

Perovskite solar cells (PSCs) have developed rapidly with simplified planar structures, in which the electron transport layer (ETL) is one of key components for high efficiency. As most widely used ETLs PSCs, a tin dioxide (SnO2) ETL usually obtained by thermal annealing at around 150 °C, complicates fabrication process and confines application PSCs onto thermally sensitive flexible substrates. Here, we adopted an annealing-free first time, negative pressure evaporation (NPE) method, to quickly prepare SnO2 (NPE-SnO2) within 1 minute room temperature from commercial aqueous colloid. The NPE here significantly improves surface morphology conductivity layers compared traditional annealed ones (A-SnO2). Detailed characterizations reveal that increased oxygen vacancies reduced hydroxyl defects contribute higher NPE-SnO2 less interfacial recombination PSCs. Therefore, PSC delivers improved fill factor (FF) 82.33% power conversion efficiency (PCE) 23.07%, highest value based on SnO2. To conclude, universal technique obtain high-quality semiconductor films their wet state min opens up possibility fabricating functional without annealing.
