Summary: Controlling oxygen vacancies in SnO2_x is crucial for efficient and stable perovskite solar cells (PSCs). However, most research only focuses on the results without analyzing the underlying phenomenological part of the strategy. This study reveals a new beneficial effect of controlling oxygen vacancies in SnO2_x by examining its role in suppressing unfavorable perovskite phase transitions and facilitating formamidinium cation retention at the interface. The findings emphasize the genuine necessity of reducing oxygen vacancies in SnO2_x.

Summary: The introduction of plasmon induced energy transfer (PIET) is a promising approach to improve the photo-electrochemical (PEC) responses on metal-oxide based photoelectrodes. This study demonstrates effective localization of a plasmon-induced near-field on a photoelectrode via patterned Au NP assemblies (Au-PAT) that enhances the PEC responses for oxidation reactions. The optimized grating pitch of Au-PAT enhances the light absorption efficiency and increases the interband transition rate via PIET.

Summary: Silicon is a promising active material for lithium-ion batteries with a high theoretical capacity. However, its fabrication requires complicated and high-cost processes to improve cyclic performance. Herein, we report a one-step wet ball-milling process to fabricate submicron silicon particles coated with a polyacrylonitrile (PAN) layer, which enhances electrolyte wettability and increases lithium-ion pathways on the silicon surface. These improvements result in a stable solid electrolyte interphase layer and reduced internal resistance of the electrodes. The silicon anodes with optimal particle size and PAN layer exhibit superior performance even at ultra-fast current density, and when combined with an NCM712 cathode, a full-cell demonstrates excellent performance.
