Chelating Coordination Regulates Perovskite Crystallization and Defect Passivation in Sn–Pb Perovskite Solar Cells

open access: yesSmall, EarlyView.
A chelating coordination strategy using ethylenediamine diacetate (EDDA) is introduced to regulate crystallization and passivate defects in Sn–Pb perovskite solar cells. Interfacial coordination at both buried and top surfaces suppresses Sn2+ oxidation, reduces defects, and enhances charge extraction, enabling over 23% efficiency with improved voltage,

HRTEM Imaging and Mechanistic Insights Into Carbon Nanotube Nucleation and Growth on Fe Nanocatalysts in a Thermal Plasma

open access: yesSmall Methods, EarlyView.
Carbon nanotubes (CNTs) were successfully debundled from Tuball soots produced using iron nanocatalysts in arc discharge thermal plasma and distributed on monolayer graphene for HRTEM imaging for mechanistic insights into CNT synthesis. Zigzag single‐wall or double‐wall CNTs were identified.

Automated Identification of Thermal Transitions in Conjugated Material Thin Films Using In Situ Optical Spectroscopy

open access: yesSmall Methods, EarlyView.
This study demonstrates the effectiveness of in situ UV−vis coupled with automated data analysis, namely, ATLAS, for fast and reliable identification of multiple thermal transition in conjugated polymer thin films. This ATLAS method will significantly accelerate the understanding of the phase behavior of D‐A polymers with important implications for ...
