Role of Cocatalyst on Sn‐Doped Hematite Photoanodes for Photoelectrochemical Glycerol Oxidation: Enhancing the Selectivity Toward C3 Molecules in Alkaline pH

Small Structures, Volume 7, Issue 4, April 2026.
The upgrading of glycerol, a low‐value and abundant byproduct of the biodiesel industry, to higher‐value chemicals is an attractive proposition. Photoelectrochemical (PEC) glycerol oxidation is a sustainable and cost‐effective approach for converting glycerol into fuels by harnessing solar energy.

A Platinum (II) Polyyne Oligomers Donor for Efficient Ternary Organic Solar Cells

Solar RRL, Volume 10, Issue 6, 29 March 2026.
Platinum (II) polyyne oligomers P5 are used as a donor in a ternary organic solar cell. The average power conversion efficiency of 16% surpasses the international record for [Pt] (II) polyyne oligomers. PC71BM speeds up the rise time for electron transfer and slows down the recombination time.

Surface‐State–Regulated Product Distribution in Photothermal CO2 Hydrogenation Over MXene‐Based S‐Scheme Catalyst

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
This work establishes an MXene‐based S‐scheme heterojunction in which the cooperative interplay among metallic Ni, surface NiOx domains, and conductive Ti3C2Clx drives efficient charge separation and photothermal coupling. Progressive evolution of Ni surface states regulates the CH4/CH3OH product distribution by modulating interfacial energetics and ...

Gas Quenching‐Mediated Crystallization for Optoelectronic‐Grade Pb–Sn Perovskite Films

Solar RRL, Volume 10, Issue 6, 29 March 2026.
Gas quenching (GQ) is introduced as a simple, ecofriendly alternative to antisolvent quenching for Sn–Pb perovskites. By slowing crystallization, GQ produces smoother, more uniform films with fewer pinholes. The method enhances reproducibility and device performance, increasing power conversion efficiency from 18.3% to 19.1% and improving open‐circuit ...

Revealing the Energy Level and Charge Dynamics Interplay in Mixed Pb‐Sn Perovskite Solar Cells with Novel Phenoxazine and Phenothiazine Self‐Assembled Monolayers

Solar RRL, Volume 10, Issue 6, 29 March 2026.
Carbazole‐based self‐assembled monolayers (SAMs) have proven effective as HTLs in perovskite solar cells (PSCs). However, the energy alignment with narrow‐bandgap lead‐tin (Pb‐Sn) perovskites is suboptimal. Here, we design four phenoxazine/phenothiazine SAMs.

Hybrid TiN ‐ MXene Photoanodes Drive Efficient Photoelectrochemical Water Splitting

Solar RRL, Volume 10, Issue 5, 12 March 2026.
The photoelectrochemical (PEC) system based on an optimized TiO2‐MXene‐TiN hybrid (MXene:TiN 1:4 wt %) hybrid network sensitized with CdS/CdSe/ZnS QDs yields a photocurrent density of 15.80 mA cm−2 under 1 sun illumination (AM 1.5G, 100 mW cm−2, having 55% higher than control TiO2/QDs device (7.20 mA cm−2).

Thickness‐Engineered FAPbI3 Absorber Layer with Average Visible Transparency Above 24%

Solar RRL, Volume 10, Issue 5, 12 March 2026.
Formamidinium‐based perovskite (FAPbI3) solar cells are attracting significant attention owing to their optimal bandgap, which is well suited for approaching the maximum theoretical efficiency. In this study, we present a straightforward strategy to realize efficient semitransparent solar cells by carefully tuning the active‐layer thickness and ...
