A Universal Interfacial Dipole Strategy for Defect Suppression in Inverted Perovskite Solar Cells With Tunable Bandgaps

Advanced Functional Materials, EarlyView.
A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...

Convenient syntheses of fullerynes for ‘clicking’ into fullerene polymers

Designed Monomers and Polymers, 2017
Alkyne-functionalized fullerenes (fullerynes) were designed and conveniently synthesized via Bingel reaction in one step with high yields. They were used to react with azido-functionalized polystyrene (PS) via Huisgen [3 + 2] cycloaddition ‘click ...

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Vacancy decay in endohedral atoms: the role of non-central position of the atom

, 2010
We demonstrate that the Auger decay rate in an endohedral atom is very sensitive to the atom's location in the fullerene cage. Two additional decay channels appear in an endohedral system: (a) the channel due to the change in the electric field at the ...
