Singlet Exciton Fission

Elucidating the quantum mechanical dynamics underlying the process of Singlet Exciton Fission in one of our main research goals. This could hold the key to a new generation of highly efficient photovoltaics (PVs)

 

The Quantum Mechanics of Singlet Exciton Fission 

The quantum mechanical mechanism underlying singlet fission is very active area of research. Recently, we have made several breakthroughs in this area using novel ultrafast spectroscopy techniques. Our results have demonstrated how coupling of electronic and nuclear degrees of freedom in molecular systems can give rise extremely fast and efficient process on sub 100s timescales. 

Singlet fission offers a rich test bend to understand the fundamental limits of excitonic process in molecular semiconductor. These results are opening up new avenues to understand and control the properties of molecular semiconductors.
