Glycerol formal is reported as a green solvent for processing efficient and stable quasi-2D (n = 5) metal halide perovskite solar cells. Abstract Despite the remarkable advances in the field of perovskite photovoltaics, the use of toxic solvents for their fabrication poses a significant challenge to their scale-up and commercialization. The...

Herein, a hydrogel electrolyte is designed via the combination of tetramethyl urea (TMU) additive, Zn(OTf)2 and polyvinyl alcohol (PVA) matrix. By leveraging the interactions between TMU with both hydrophilic and hydrophobic groups, as well as PVA, H2O, and Zn2+, the water activity and Zn2+ solvation structure are regulated, resulting in the development...

The fluorinated COF film (TpBD-2F), grown in situ on the Zn substrate, features zincophilic and hydrophobic 1D fluorinated nanochannels, which can regulate the plating/stripping behavior of Zn2+, thereby inhibiting the formation of Zn dendrites and interfacial side reactions. Abstract Zinc (Zn) emerges as an ideal anode for aqueous-based...

In this work, the discovery of a new family of layered crystalline LiMCl6 (M = Ta/Nb) compounds is presented. The ionic conductivity and Li intercalation mechanism in LiTaCl6 is investigated in the context of an all-solid-state battery. These findings open the door to a wide range of substituted layered halides with competing ionic and electronic...

This study presents a strategy to directly deposit SnO₂ quantum dots (QDs) on perovskite using ethylenediamine in p–i–n PSCs. By mitigating sputtering damage and due to the high transmittance of SnO₂ QDs, a transparent solar cell with a bifacial factor of 99% is implemented, and a four-terminal all-perovskite tandem cell with a PCE of 27.0% is realized....

A phosphorus bridging strategy is demonstrated for constructing iron and cobalt binuclear SACs (i.e., FeN4-P-CoN4) supported on nitrogen-doped graphitic carbon (P/FeCo-NC). Density functional theory (DFT) calculations suggested that phosphorus bridging of Co sites significantly improved the H* adsorption ability of the Fe sites, thereby boosting the...
