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...
Tin, the enabler

Tin, the enabler

Congratulations to Chidozie Onwudinanti for publishing his first first-author paper ‘Tin, The Enabler—Hydrogen Diffusion into Ruthenium’. (Open Access) Combining DFT calculations and several chemical bonding and charge analysis techniques, Onwudinanti et al...
The small cations in perovskites

The small cations in perovskites

In collaboration with group of Ni Zhao from the Chinese University of Hong Kong, in our recent publication on Advanced Materials, we reveal the mysterious role of small alkali ions in mixed perovskites in stabilizing the perovskite solar cells. Combining theoretical...
