The presence of the detrimental PbI2 residue at buried interface negatively affects photovoltaic performance perovskite solar cells (PSCs). However, underlying mechanism involved in formation and elimination residual has been rarely investigated, despite its critical significance for high-efficiency stable PSCs. Here, we investigated influenced by citric acid (CA) found that CA can quickly remove PbI2·DMSO complex through a competitive adsorption forming highly crystallized PbI2. This...
A series of new organic D−π−A dyes, coded as DS-1, DS-2, DS-3, and DS-4, was designed, synthesized, characterized by 1H NMR, 13C infrared spectroscopy, mass spectrometry, elemental analysis. These dyes consist a di( p-tolyl)phenylamine moiety an electron donor, cyanoacetic acid acceptor/anchoring group, different types conducting thiophene units spacers to bridge the donor acceptor. It found that both use variation in played essential role modifying and/or tuning physical properties dyes....
This paper presents rapid response colloidal photonic crystal (PC) microdots fabricated by inkjet printing, which demonstrate a fastest of ca. 1.2 s to water vapor. remarkable improvement rate could be attributed the combined effects intrinsic small size and hydrophobic transition poly(N-isopropyl acrylamide) (PNIPAm) above its lower critical solution temperature (LCST). The reversible phase PNIPAm modifies hydrophilic–hydrophobic balance polymer interface, leads modulation wetting...
The surface defects of the organometallic perovskite play an important role in photovoltaic performance solar cells, which depress conversion efficiency and cause photocurrent hysteresis.
Abstract The rate‐determining process for electrochemical energy storage is largely determined by ion transport occurring in the electrode materials. Apart from decreasing distance of diffusion, enhancement ionic mobility crucial transport. Here, a localized electron enhanced mechanism to promote ultrafast proposed. Theoretical calculations and analysis reveal that highly electrons can be induced intrinsic defects, migration barrier ions obviously reduced. Consistently, experiment results...

A three-dimensional porous vanadium oxide was anodically deposited onto graphite substrates (denoted as ) at 0.7 V from an aqueous solution containing 25 mM and 5 . Through annealing temperatures up to , the thermal stability of preserved its morphology excellent capacitive performances in 3 M KCl (pH 2.4). X-ray photoelectron spectroscopic analysis revealed mixed valence nature oxy-/hydroxyl-vanadium species which amount not significantly affected by varying temperature. maximal specific...
Three donor–(π-spacer)–acceptor dyes, coded as DS-3, DS-5 and DS-6, were designed synthesized for dye-sensitized solar cells (DSSCs). These dyes possess the same donor (triarylamine) acceptor/anchoring group (2-cyanoacrylic acid), but varied π-spacers consisting of a combination thiophene and/or 3,4-ethylenedioxythiophene (EDOT) units. They evaluated by photophysical electrochemical measurements well in nanocrystalline TiO2-based DSSCs fabricated using them light-harvesting sensitizers. The...
Large-area Ag nanowires are ordered by spontaneous spreading of volatile droplet on a wettable solid surface. Compared with other orientation methods, radial shaped oriented in large ring region obtained an extremely short time. Furthermore, the transferred and aligned into one direction. Based hydrodynamics, coactions among microfluid, gravity effect adhesion substrate clearly revealed. This method opens efficient way for extreme economic, "green" commercial producing nanowire arrays.
Sensing techniques are often required to not only be versatile and portable, but also able enhance sensor information. This paper describes demonstrates a new approach chemical signal analysis that we call fluctuation-enhanced sensing. It utilizes the entire bandwidth of in contrast more conventional approaches rely on dc response. The principle holds prospects for significantly reducing necessary number sensors artificial noses tongues, it can provide improved sensitivity.
