How an intermetallic Li2Te–LiTe3 interlayer stabilizes the lithium metal–argyrodite solid-state electrolyte interphase and the failure mechanisms that occur without it, is examined. The intermetallic bilayer impedes electrolyte decomposition, preventing the reaction-driven voiding in lithium metal that occurs otherwise. Since lithium metal reacts...

This study elucidates the formation dynamics and film structure of 2D-Dion-Jacobson phase on a template of 3D triple-cation perovskite films via in situ X-ray scattering. The solvent-induced surface reconstruction of the template allows the control of phase and phase distribution in 2D films. The tailored energy landscape of 2D/3D heterostructures...

A novel single-molecule catalyst (SMC) that features a nickel-based inorganic complex anchored to a graphene acid substrate is developed, which undergoes an in situ geometric transformation under alkaline conditions, creating a paramagnetic center. When subjected to a magnetic field, this facilitates spin-selective electron transfer, thereby enhancing...

In perovskite solar cells (PSCs), engineering the interface between perovskite absorber thin films and charge transport layers has been pivotal. Self-assembled monolayers (SAMs) in the electron-blocking layer have improved contact efficiency, reducing interfacial recombination. SAM growth models and plasma treatment for conformal SAM growth are investigated,...

Thiophene rings are fused on the donor (D), π, and acceptor (A) units, respectively, to extend the conjugation length and fine-tune molecular conformation of the classic D–π–A-type benzotriazole (BTA)-containing polymer. Thiophene fusion on the π-bridge produces the linear backbone and the highest carrier mobilities, contributing to a champion power...

An improved zinc transfer ability from surface conduction is achieved by group modification of polymer units. Experimental results and theoretical simulations reveal that when modified with carbonylation side groups the interaction between zinc and polymer skeleton is weakened and this contributes to improved zinc ion transfer number, which endows...
