Organic molecular photovoltaics (OPVs) is a typical excitonic and energetically disordered PV technology, whose operations are complex and require advanced modelling technique. In this talk, I will introduce a cheap modelling framework that enables theoretical connections between molecular properties and device properties. The model successfully links three scales of models: Marcus-Levich-Jortner molecular model, kinetic rate model, and the drift-diffusion model, theoretically linking local excitonic (LE), charge transfer (CT), and charge separated (CS) state and allowing direct investigations of microscopic molecular properties from macroscopic device properties. I will highlight the important role of CT state, as well as its interactions with LE and CS state. I will also talk about applications and modifications of the model, in particular, I will discuss about charge transport, energy loss, and spectroscopy analysis7,8 for OPVs.
