Defect Suppression via Tailoring Functionalized Additives for Efficient and Stable CsPbI3 Perovskite Solar Cells

open access: yesCarbon Energy, EarlyView.
This study proposed a structure‐designed benzohydrazide derivative, namely 4‐methoxybenzohydrazide (MeOBH), as an additive to regulate crystallization, passivate defects, optimize energy‐level structure, and enhance phase stability of β‐CsPbI3 perovskite films.

A “Two‐Pronged” Strategy Boosting the Activity and Stability of Nickel–Iron Catalysts Toward Anion Exchange Membrane Water Electrolysis

open access: yesCarbon Energy, EarlyView.
A “two‐pronged” strategy has been developed to construct a substrate‐strengthened, organophosphorus‐protected nickel‐iron electrode for efficient and robust OER electrocatalysis. Owing to the reinforced catalyst–substrate interaction and minimized active site loss by organophosphorus protection, the integrated electrode serves as an robust and ...

Data‐Driven Design of Scalable Perovskite Film Fabrication via Machine Learning–Guided Processing

open access: yesCarbon Energy, EarlyView.
Considering complex process parameters and poor reproducibility in perovskite thin film fabrication, this study uses machine learning to analyze and predict high‐dimensional process variables. The Random Forest model, identified as the most effective, can effectively analyze and rapidly predict optimal process parameters from extensive data.
