The defect passivation of perovskite films is an efficacious way to further boost the power conversion efficiency (PCE) and long-term stability solar cells (PSCs). In this work, ionic liquids (ILs) 1-butyl-2,3-dimethylimidazolium chloride ([BMMIm]Cl) are used as a modification layer in carbon-based CsPbBr3 PSCs without hole-transporting material (HTM) for passivating surface defects. preliminary results demonstrate that [BMMIm]Cl modifier passivates defects film reduces valence band close...
Abstract The sodium dual ion battery (Na‐DIB) technology is proposed as highly promising alternative over lithium‐ion batteries for the stationary electrochemical energy‐storage devices. However, sluggish reaction kinetics of anode materials seriously impedes their practical implementation. Herein, a Na‐DIB based on TiSe 2 ‐graphite reported. high diffusion coefficient Na‐ions (3.21×10 −11 –1.20×10 −9 cm s −1 ) and very low Na‐ion barrier (0.50 eV) lead to fast electrode kinetics, alike in...

With the rapid rise in perovskite solar cells (PSCs) performance, it is imperative to develop scalable fabrication techniques accelerate potential commercialization.

Abstract Mixed‐cation perovskite solar cells (PSCs) have attracted much attention because of the advantages suitable bandgap and stability. It is still a challenge to rationally design modify perovskite/tin oxide (SnO 2 ) heterogeneous interface for achieving highly efficient stable PSCs.

Lead halide perovskite nanocrystals, such as CsPbBr3, exhibit efficient photoluminescence (PL) up-conversion, also referred to anti-Stokes (ASPL). This is a phenomenon where irradiating nanocrystals up 100 meV below gap results in higher energy band edge emission. Most surprising that ASPL efficiencies approach unity and involve single-photon interactions with multiple phonons. unexpected given the statistically disfavored nature of multiple-phonon absorption. Here, we report rationalize...
An all-inorganic cesium lead bromide (CsPbBr3) halide has attracted growing attention for carbon-based perovskite solar cells (PSCs) owing to its inherent stable lattice in thermal and/or moisture ambient. The main drawback CsPbBr3 PSCs is the low power conversion efficiency (PCE) caused by serious charge recombination at surfaces device interfaces. To address this problem, an interface engineering strategy modifying a polyvinyl acetate (PVAc) polymer with carbonyl group of CsPbBr3/carbon...
Artificial photosynthesis of H2O2, an environmentally friendly oxidant and a clean fuel, holds great promise.
