Simulating OLEDs.

Use the power of device simulation to understand your experimental data from thin film devices such as Organic Solar cells, sensors, OFET, OLEDs, Perovskite solar cells, and many more. Gpvdm contains both electrical and optical models to produce accurate and predictive device simulations, which when combined with experimental results will enable you to reach higher impact journals. Features include:

Take your research to new levels by combining experiment and simulation.


The model can simulate:

The model makes it easy to study the influence of material parameters such as mobility, energetic disorder, doping and recombination on device performance. All internal device parameters are easily accessible through the graphical interface .

Technical details

The model solves the device equations in steady state or time domain, in 1D or in 2D. Specifically, the model solves both electron and hole drift-diffusion, and carrier continuity equations in position space to describe the movement of charge within the device. The model also solves Poisson's equation to calculate the internal electrostatic potential. Recombination and carrier trapping are described within the model using a Shockley-Read-Hall (SRH) formalism, the distribution of trap sates can be arbitrarily defined. A fuller description of the model can be found in the here, in the associated publications and in the documentation.
