Visiting scholar

We welcome a new visiting postdoc Dr. Limei Wang from Shenzhen University to join us. Dr. Wang recived her PhD in Chemical Engineering and Technology from Xiamen and Yanshan University and she is an expert on nanomaterials and photocatalysts. Welcome to the group and look forward to working together!

New Publication

Wenhao’s invited perspective article entitled “Light-Emitting Organic Semiconductor-Incorporated Perovskites: Fundamental Properties and Device Applications” has been published in J. Phys. Chem. Lett. Congratulations! Read the story here.

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.

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!

New postdoc

The group warmly welcomes a new postdoc fellow Dr. Chenjian Lin joining us. Chenjian received his PhD in Physical / Organic Chemistry from Northwestern University with Prof. Michael Wasielewski. Chenjian will work on synthesis of novel OSiPs and heterostructures. Welcome to the group. Look forward to working together!

New Student

Jeonghui Kim joins our group as a first-year graduate student. Jeonghui receives her BS and MS in Chemical Engineering from Inha University. She is interested in both halide perovskite and polymer materials. Welcome to the group!
