 Research interests

Ab initio modeling of excitons in functional molecules for their applications in photonic and photovoltaic devices.

Development of predictive models and methods for exploring and understanding charge transfer (CT) states, which play a major role in both exciton dissociation and charge recombination processes in organic photovoltaic (OPV) devices.

Understand intersystem crossing rates between singlet and triplet CT states, which can provide a better understanding of the spin-dependent charge-recombination processes in donor/acceptor heterojunctions.

  • Dissipative Particles Method (DPD) to the study the morphology in OPV devices, which is a method used for systems in scale between atomistic and macroscopic sizes. The primary advantage of DPD is its faster simulation times compared to traditional molecular dynamics
