Quasi-two-dimensional (2D) perovskites are highly promising light-harvesting materials for commercialization of perovskite solar cells (PSCs) owing to the excellent stability. However, coexistence multiple n-value species in 2D often causes increased complexities crystallization that can negatively affect eventual photovoltaic performance. Herein, we present a binary solution based strategy via introducing nontoxic and widely accessible CH3COOH (HAc) as co-solvent preparing high-quality...
Although the photovoltaic performance of perovskite solar cells (PSCs) has reached commercial standards, unsatisfactory stability limits their further application. Hydrophobic interface and encapsulation can block damage water oxygen, while instability induced by intrinsic residual strain remains inevitable. Here, in a two-dimensional (2D) Ruddlesden-Popper (RP) film is investigated X-ray diffraction atomic force microscopy. It's found that spacer cations contribute to even though they are...
Two dimensional Dion-Jacobson (2D DJ) perovskite has emerged as a potential photovoltaic material because of its unique optoelectronic characteristics. However, due to low structural flexibility and high formation energy, extra assistance is needed during crystallization. Herein, we study the solvent effect on film trap states 2D DJ perovskite. It found that nucleation process can be retarded by coordination, which proved in situ optical spectra. As benefit, out-of-plane oriented...
Direct growth of graphene films on glass is great importance but has so far met with limited success. The noncatalytic property results in the low decomposition ability hydrocarbon precursors, especially at reduced temperatures (<1000 °C), and therefore amorphous carbon (a-C) are more likely to be obtained. Here, we report hydrogen influence structural electrical properties deposited quartz 850 °C by hot-filament chemical vapor deposition (HFCVD). revealed that obtained a-C were all...
A monolithic catalyst was fabricated through an emulsion-templating method, postpolymerization modification, and in situ loading of active constituents. To achieve a high specific surface area, divinylbenzene (DVB) solely employed as the monomer, while porous structure adjusted with porogen content types initiators. Then, anchor points were introduced on pore wall nitration amination polymeric scaffold. Using controlled "silver mirror reaction", catalysts obtained after silver nanoparticles...
Existing studies have indicated the potential role of non-invasive physical health indicators as an early detector mild cognitive impairment (MCI) in older adults. However, evidence is lacking determining appropriate for screening decline each domain. Therefore, current study aimed to establish a comprehensive profile association with performance. The present utilized three-year longitudinal cohort design, data from China Health and Retirement Longitudinal Study (CHARLS). 4,869 participants...
N-Doped graphene glass was prepared through a novel plasma-assisted HFCVD approach, which exhibited significantly enhanced voltage generation for energy harvesting.
High-performance energetic materials require good balance between energy and safety, which may be achieved through structural design. Herein, an compound containing a furazan-triazole backbone linked by methylene bridges systematic series of corresponding salts were synthesized, characterized structurally, subjected to various performance tests. All the target compounds possessed impact sensitivities (IS > 24 J) friction (FS 240 N), as well acceptable detonation velocities (D 7756 m...
Interfacial modification is a promising strategy to fabricate highly efficient perovskite solar cells (PSCs). Nevertheless, research studies about optimization for the performance of Dion–Jacobson (DJ)-phase quasi-2D PSCs by underlying surface are rarely reported. The relevant influence interfacial on defect regulation in bulk and at interface still unexplored. Herein, an interlayer polyaspartic acid (PASP) was introduced hole transporting layer absorber regulate both film quality property...
Ge-doped CZTSSe thin films were obtained by covering a Ge layer on CZTS precursors, followed selenization process. The effect of the thickness morphologies and structural properties studied. It was found that doping could promote grain growth to form compact film. lattice shrank in top-half film due smaller atomic radius Ge, leading formation tensile stress. According thermodynamic analysis, Sn easier be selenized than Ge. Thus, preferred remain surface increased roughness when thin. CZTSe...
Ideal amorphous carbon prepared at low temperature by e-beam evaporation has potential as buffer layers for Ge growth on Si.
