Abstract A facile and controllable strategy, which combines solvothermal treatment with ex situ nitrogen doping by using urea saturated alcohol solution or monoethanolamine as source, is used to prepare flexible, freestanding, compact nitrogen‐doped delaminated Ti 3 C 2 (abbreviated N‐Ti ) film electrodes for symmetric electrochemical capacitors (ECs). Compared the N sites from in solid doping, those of enable larger contributions capacitance through regulating species content. As a result,...
Elpasolite Cs 2 AgBiBr 6 also known as double perovskite has been touted in recent years a promising alternative to the lead‐based for light harvesting. Its structure and properties mainly stem from replacement of Pb 2+ cation with pair aliovalent silver (Ag + ) bismuth (Bi 3+ cations. Although elpasolite exhibits improved stability, its photophysical device performance are inferior those Pb‐based perovskites. To date, numerous efforts have geared toward development efficient solar cells....
Nitrides MAX have attracted ever-growing interest owing to its unique metallic and ceramic characteristics properties. Here, we report on the synthesis of highly purified Ti 2 AlN 4 3 powders from Ti, Al TiN by a facile atmosphere sintering method. The obtained nitrides show pure phase excellent layered structure. Except for composition difference raw materials, both can be sintered same temperature holding time, which thus makes less processing time usage parameters as compared previously...
A perovskite solar cell (PSC) featuring a mesoporous architecture can facilitate layer formation over large area via increasing the number of heterogeneous nucleation sites. The morphology electron transport (ETL) and its interface with is one key factors to boost performance PSC. Tin dioxide (SnO2) considered as promising ETL in PSCs owing high carrier mobility, good transmittance, deep conduction band level, efficient photoelectron extraction. Generally, SnO2 (m-SnO2) has higher...
PSS is a commonly used hole-transport layer (HTL) in inverted perovskite solar cells (PSCs) due to its compatibility with low-temperature solution processing. However, it possesses lower conductivity than other conductive polymers and metal oxides, along surface defects, limiting photovoltaic performance. In this study, we introduced two-dimensional Ti3C2Tx (MXene) as an additive the PEDOT:PSS HTL varying doping concentrations (i.e., 0, 0.03, 0.05, 0.1 wt.%) tune electrical of modify...
The synergistic effect of high-quality NiOxhole transport layers (HTLs) deposited by ion beam sputtering on ITO substrates and the Ti3C2TxMXene doping CH3NH3PbI3(MAPI) perovskite is investigated in order to improve power conversion efficiency (PCE) p-i-n solar cells (PSCs). 18 nm thick NiOxlayers are pinhole-free exhibit large-scale homogeneous surface morphology as revealed atomic force microscopy (AFM). grazing-incidence x-ray diffraction showed a 0.75% expansion face-centered cubic...
Improving the energy alignment between charge-transport layers and perovskite is crucial for further enhancing photovoltaic performance of tin-based solar cells (PSCs). Herein, role Ti3C2Tx MXene in a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) hole transport layer (HTL) on properties PSCs investigated as function its concentration. An improved film formation with reduced pinhole density more uniform contact potential difference noted when embedded PEDOT:PSS HTL. The...
Lithium–sulfur (Li–S) batteries have attracted much attention due to their high energy density and cost efficiency. However, the drawbacks such as polysulfide shuttle effect low electrical conductivity of active sulfur material result in poor cycling performance. In this work, we endeavored overcome these problems by applying a highly engineered bilayer single-walled carbon nanotubes (SWCNTs). Two monolayers aligned SWCNTs were deposited on glass fiber separator using modified...
Recently discovered two-dimensional (2D) transition metal carbides and nitrides (MXenes) have received tremendous attention because of their unique electrical, optical chemical properties.These exceptional properties make them a suitable candidate for variety applications including multimodal tumor therapy by photothermal effect.In this work, we demonstrate how to reduce the size 1-5 µm large Ti3C2 monolayer MXene sheets into ultrasmall 100-160 nm nanosheets applying consecutive...
