Fully printed flexible perovskite solar modules with improved energy alignment by tin oxide surface modification

Lirong Dong, Shudi Qiu, Jose Garcia Cerrillo +14

Fully printed flexible perovskite solar cells (f-PSCs) show great potential for the commercialization of perovskite photovoltaics owing to their compatibility with high-throughput…

Impact of the Ligand Shell on Structural Changes and Decomposition of All-Inorganic Mixed-Halide Perovskite (CsPbX3) Nanocrystals under X-Ray Illumination

Jan Wahl, Philipp Haizmann, Christopher Kirsch +9

We show that the decomposition of caesium lead halide perovskite nanocrystals under continuous X-ray illumination depends on the surface ligand. For oleic acid/oleylamine, we obser…

Porphyrin-functionalization of CsPbBrI/SiO core-shell nanocrystals enhances the stability and efficiency in electroluminescent devices

Jan Wahl, Manuel Engelmayer, Mukunda Mandal +7

Surface ligand exchange on all-inorganic perovskite nanocrystals of composition CsPbBrI reveals improved optoelectronic properties due to strong interactions of the nanocryst…

Light amplification by stimulated emission from an optically pumped molecular junction in a scanning tunneling microscope

K. Braun, A. M. Kern, X. Wang +5

Here, we introduce and experimentally demonstrate optical amplification and stimulated emission from a single optically pumped molecular tunneling junction of a scanning tunneling…
