New Publication

Kang’s work entitled “Suppressing phase disproportionation in quasi-2D perovskite light-emitting diodes” has been published in Nature Communications. Congratulations!

We demonstrate that extending the π-conjugation length and increasing the cross-sectional area of the organic semiconducting ligand enables perovskite thin films with dramatically suppressed ion transport, narrowed phase distributions, reduced defect densities, and enhanced radiative recombination efficiencies. Consequently, we achieved efficient and stable deep-red light-emitting diodes with a peak EQE of 26.3% and a half-life of ~220 h under a constant current density of 0.1 mA/cm2. Read the story here.

New publications

Blake’s work entitled “Amine-Thiol/Selenol Chemistry for Efficient and Stable Perovskite Solar Cells” has been published in J. Phys. Chem. C as part of The Journal of Physical Chemistry virtual special issue “Early-Career and Emerging Researchers in Physical Chemistry”. Congratulations! Read the story here.

Visiting student

The group warmly welcomes a new visiting undergrad student joining us. Devansh Drolia is a senior chemical engineering student in Birla Institute of Technology and Science (BITS) Pilani. Devansh will work on fabrication and characterization perovskite solar cells. Welcome to the group!
