SnPb alloyed perovskite QDs

SnPb alloyed perovskite QDs

In collaboration with Prof. Qing Chen (Japan), Dr. Feng Liu, Junke Jiang discovered small amount of Na improves significantly the optoeletronic properties of An-Pb perovskite alloy Quantum Dots. Through incorporation of Na+ , we have realized for the first time...
CsRb stablize Perovskite LEDs

CsRb stablize Perovskite LEDs

In a joint experimental and theoretical work, Lei shows that binary cations of Cs and Rb improves the operation stability of perovskite LEDs. The work is published open access on Advanced Materials. A short summary of the work can be found below: Perovskite light...
Small ions plus large ions

Small ions plus large ions

Haibo Xue, in collaboration with colleagues from The Chinese University of Hong Kong has proven that large cations like Guanidium can fit into the perovsikte lattice with simultaneous introduction of the small-size ions like Cs+ and Br-. In this research, FAPbI3 was...
The absolute energy levels

The absolute energy levels

Our paper “Absolute energy level positions in tin and lead based halide perovskites” is published today on Nature Communications for publication. Here, we address one of the most debated topics in the material class of metal halide perovskites: the absolute energy...
Fluoride protects perovskite PV

Fluoride protects perovskite PV

Our work in collaboration with Peking University on the effective passivation of several types of vacancy defects in metal halide perovskite for highly stable perovskite solar cells by small anions is published today on Nature Energy. We obtain stable perovskite solar...
