• Photophysics of organic and hybrid molecules

We investigate the photophysical processes 

from absorption to emission. Understanding 

the electronic structure and the dynamics of 

photoexcited species, for example, singlets, triplets, charge-transfer complexes is crucial for optoelectronic diodes including organic and perovskite PVs and LEDs. We use linear spectroscopic tools and non-linear spectroscopic techniques.

• Organic/perovskite solar cells and light-emitting diodes

We fabricate and characterize organic/perovskite

solar cells and organic/perovskite light-emitting 

diodes. Organic solar cells convert light to 

Based on understanding on photophysical and electrical properties of organic semiconductors, electricity, and organic light-emitting diodes generate light from electricity. 

we aim to enhance efficiency.
