Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

Advanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

Controlling Near‐Infrared Fluorescence‐to‐Phosphorescence Ratios and Triplet Lifetimes in Rhodium(I) Dimers via Primary and Secondary Coordination Sphere Effects

Angewandte Chemie, EarlyView.
RhI dimers with bridging aryl isocyanide and di‐phosphine ligands show NIR‐I or NIR‐II fluorescence/phosphorescence, depending on the ligands and conformational rigidity at the Rh2 core. Rh‐Rh interactions can be tuned by peripheral modification of the aryl isocyanide ligand, resulting in a rigid Rh2 core and improved photophysical properties ...
