The environmental toxicity of Pb in organic–inorganic hybrid perovskite solar cells remains an issue, which has triggered intense research on seeking alternative Pb-free perovskites for applications. Halide based group-VA cations Bi3+ and Sb3+ with the same lone-pair ns2 state as Pb2+ are promising candidates. Herein, through a joint experimental theoretical study, we demonstrate that Cl-incorporated methylammonium Sb halide (CH3NH3)3Sb2ClXI9–X show promise efficient absorbers cells....
Abstract Relaxor ferroelectric polymers exhibiting a giant electrocaloric effect (ECE) can potentially be used to create next‐generation solid‐state coolers. Under an electric field, poly(vinylidene fluoride‐trifluoroethylene‐chlorofluoroethylene) terpolymer goes through large dipolar entropy change producing high adiabatic temperature (Δ T ECE ). This work resolves the molecular origins of behind field‐induced dipole switching. A Fourier transform infrared spectroscopy equipped with voltage...
A fabrication technique inspired by an old Chinese calligraphy tradition is developed to fabricate organic solar cells and modules.
Thermoresponsive materials, in particular those exhibiting switchable optical transmittance via temperature change, have been widely used different applications. If the required change is within seasonal changes, would consume low energy or be autonomous. Here, a solid-state thermoresponsive phase-changing copolymer (TPCC) film has demonstrated, with large modulation between room and hot temperatures (>28 °C). The polymer comprises hydrophilic poly(hydroxyethyl acrylate) (HEA) cross-linked...
Hydroxyl groups on the surface of ZnO films lead to chemical decomposition CH3NH3PbI3 perovskite during thermal annealing, which limits application as a facile electron-transporting layer (ETL) in solar cells. In this work, we report new recipe that leads substantially reduced hydroxyl resulting by employing polyethylenimine (PEI) replace generally used ethanolamine precursor solutions. Films derived from PEI-containing precursors are denoted P-ZnO and those ethanolamine-containing E-ZnO....
Cesium lead bromide quantum dot (CsPbBr3 QD) is emerging as a promising luminescent material for gamma ray detection. However, its intensive self-absorption traps the photons generated and diminishes scintillation light yield. The magnified at high CsPbBr3 QD loading large scintillator volume, which are required to effectively attenuate photons. We report liquid loaded with up 40 wt % of QDs. Pyrromethene 580 (PM-580), fluorescent dye, was co-dissolved in solution fluorescence resonance...
Existing haptic actuators are often rigid and limited in their ability to replicate real-world tactile sensations. We present a wearable artificial muscle skin (HAMS) based on fully soft, millimeter-scale, multilayer dielectric elastomer (DEAs) capable of significant out-of-plane deformation, capability that typically requires or liquid biasing. The DEAs use thickness-varying structure achieve large displacement force, maintaining comfort wearability. Experimental results demonstrate HAMS...
Abstract QD color conversion with UV microLEDs shows great potential for full‐color microdisplays high brightness, superior quality, and resolution.
In this paper, a novel conductive hydrogel was made by one-pot method at 60 °C for 12 hours in one step without any cross-linking agent. The composited of Ti 3 C 2 MXene nano slices, poly(vinyl alcohol) (PVA) and poly-N-(2-hydroxyethyl acrylamide) (PHEAA), named as MXene/PVA/PHEAA hydrogel. Compared with previous methods to make hydrogel, facile fast. as-prepared highly stretchable the breaking elongation 1300% tensile strength 1.1 MPa. sheets dispersed formed three-dimensional network,...
Abstract It is well known that poor interlayer adhesion from limited diffusion and entanglement of chains across the interface main reason for anisotropy mechanical properties 3D printed parts prepared by fused deposition modeling (FDM). The present study demonstrates effects a protective atmosphere secondary treatment to improve fusion between filaments. experimental results demonstrate with nitrogen protection increase about 100% in direction filament accumulation while oxidation degree...
