A Tripartite Physics-based Model for Organic Solar Cells

TL;DRAbstract

In this paper, a tripartite macroscopic physics-based model is presented for analysis of organic solar cells (OSCs) in several aspects. This model is consisting of three sub-models (optical, electric and thermal models) which are also coupled to one another. The electric model estimates the current-voltage characteristic of an OSC considering the voltage-dependent series resistance. The 1-D optical model calculates the optical field all along the device that would be further advantageous in predicting the active layer exciton generation rate (input parameter of the electric model), optical heat generation (input parameter of the thermal model), etc. The 3-D steady-state (SS) resistive thermal model is also capable of determining the device SS temperature, also specifying the role of heat conduction, heat convection and heat radiation. These three models are verified individually with experimental data. The electric model is employed to illustrate the nonlinear series resistance in a ty
