Thermal history controls the optoelectronic response of lead halide perovskites through structure and dynamics

Lead halide perovskites are promising optoelectronic materials for photovoltaics, light emission and detection. Their efficiencies in PV now approach the detailed-balance limit, leaving stability as the principal barrier. The intrinsic instabilities studied to date centre on ionic motion within a fixed, homogeneous lat...

Advancing 1.84 eV Wide-Bandgap Perovskite Photovoltaics Beyond 20% via Single-Facet-Oriented Self-Assembled Molecules.

Uncontrolled crystal growth and structural heterogeneity in solution-processed self-assembled molecules (SAMs) remain major limitations for efficient interfacial charge transport. Herein, we report a dipole-engineered molecular strategy to regulate SAMs crystallization through the rational design of fluorinated benzimi...

Aromatic Heterocycle Ligands for Perovskite Photovoltaics: Balancing Defect Passivation and Heterostructure Formation.

Inverted perovskite solar cells (PSCs) possess great potential for improving efficiency and operating stability, but parasitic charge recombination at the interfaces still limits their performance. As additives and surface treatment agents, ammonium ligands have been reported to form either two/three-dimensional (2D/3D...
