An electron-transport layer with appropriate energy alignment and enhanced charge transfer is critical for perovskite solar cells (PSCs). In addition, interface stress lattice distortion are inevitable during the crystallization process of perovskite. Herein, IT-4F introduced into PSCs at buried SnO2 interface, which assists in releasing residual layer. Meanwhile, work function SnO2/IT-4F lower than that SnO2, facilitates from to ETL consequently leads a significant improvement power...
A molecular hole transport material retards the iodine migration and delivers high stability in a harsh 85 °C MPP test.
As a hole-transport layer (HTL) material, poly(3,4-ethylenedioxythiophene):polystyrene-sulfonate (PEDOT:PSS) was often criticized for its intrinsic acidity and hygroscopic effect that would in the long run affect stability of perovskite solar cells (Pero-SCs). alternatives, herein water-soluble two-dimensional (2D) transition metal dichalcogenides (TMDs), such as MoS2 WS2 were used HTLs p-i-n Pero-SCs. It found content 1T phase 2D TMDs is centrally important to power conversion efficiencies...
Thick, wide-bandgap materials as photoactive layers in semi-transparent Pero-SCs realized >20% AVT and ∼10% PCE.
In planar n–i–p perovskite solar cells (Pero-SCs), interfacial engineering plays a critically important role in charge extraction and transportation, hence influences the photovoltaic performances.
In this study, a room-temperature and aqueous solution-processed two-dimensional (2D) transition-metal dichalcogenide TiS2 was applied as an electron transport layer (ETL) in planar n-i-p perovskite solar cells (Pero-SCs). Upon insertion of the 2D ETL with UV-ozone (UVO) treatment, power conversion efficiency (PCE) Pero-SCs optimized to 18.79%. To best our knowledge, value should be highest date among those PCEs room-temperature-processed metal compound ETLs. More importantly, UVO-treated...
It is technically challenging to reversibly tune the layer number of 2D materials in solution. Herein, a facile concentration modulation strategy demonstrated tailor aggregation state ZnIn2 S4 (ZIS) atomic layers, and they are implemented for effective photocatalytic hydrogen (H2 ) evolution. By adjusting colloidal ZIS (ZIS-X, X = 0.09, 0.25, or 3.0 mg mL-1 ), layers exhibit significant (006) facet stacking solution, leading bandgap shift from 3.21 2.66 eV. The stacked further assembled into...
Abstract The emission peak shift caused by ion motion, especially under high bias voltage, is an obstacle to the development of blue perovskite light‐emitting diodes (PeLEDs). In this work, 3‐Aminopiperidine dihydrochloride (3AP) construct heterocyclic dication Dion‐Jacobson (DJ) PeLEDs introduced, and found that 3AP incorporation can retard halide segregation chloride loss, leading improvement spectral stability. By increasing amount (DJ phase), centers be tuned from green but excitonic...
Abstract The bottom contact in perovskite solar cells (PSCs) is easy to cause deep trap states and severe instability issues, especially under maximum power point tracking (MPPT). In this study, sodium gluconate (SG) employed disperse tin oxide (SnO 2 ) nanoparticles (NPs) regulate the interface at buried interface. SG‐SnO electron transfer layer (ETL) enabled deposition of pinhole‐free films ambient air improved by bridging effect. PSCs achieved an impressive conversion efficiency (PCE)...

Abstract Poly(3,4‐ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) can be roll‐to‐roll deposited on the substrate facilely in electronics, but its acidity and mismatched energy level limit performance stability. Herein, different metal salts are incorporated into PEDOT:PSS solution to prepare PEDOT:PSS‐A x O y (metal oxide) composite hole transport layer it is found that of inverted perovskite solar cells (PSCs) greatly enhanced. PSC using PEDOT:PSS‐MoO has achieved much higher power...
Lead-acid batteries are a reliable and cost-effective uninterrupted power supply for cars, wheelchairs, others. Recycling the spent lead-acid has increased cost could be serious pollution issue after extensive use. It is important to exploit new-generation application increase their value.

The performance of the blue perovskite light-emitting diodes (PeLEDs) is limited by low photoluminescence quantum yields (PLQYs) and unstable emission centers. In this work, we incorporate sodium bromide acesulfame potassium into a quasi-2D to control dimension distribution promote PLQYs. Benefiting from efficient energy cascade channel passivation, sky-blue PeLED has an external efficiency 9.7% no shift electroluminescence center under operation voltages 4 8 V. Moreover, half lifetime...
Enzootic nasal tumor virus 2 (ENTV2), the etiologic agent of enzootic adenocarcinoma (ENA) in goats, is highly prevalent China and causes significant economic losses to goat industry. Here we describe occurrence ENA on a Dazu black farm Chongqing City. At autopsy, cavity masses were observed within nose an affected goat; histologically, was adenocarcinoma.
