Large-Area Device Simulation

Walkthrough: Simulating Large-Area Devices

Gravure-Printed Devices via Resistor Network Modelling

OghmaNano enables the simulation of large-area photovoltaic and optoelectronic devices by transforming them into an equivalent 3D resistor–diode network. This approach makes it possible to model devices from the laboratory scale up to full-size solar modules or roll-to-roll printed electronics, while retaining realistic physical behaviour.

Arbitrary 3D device geometries can be imported or generated within OghmaNano - including hexagonal contact patterns, irregular busbars, and custom electrode layouts. These structures are automatically converted into spatially resolved electrical networks, allowing you to:

Account for shading effects with integrated optical modelling - from patterned electrodes, overhanging structures, or partial occlusion.
Automatically generate complex 3D equivalent circuits containing thousands of diodes and resistors that capture local variations in performance.
Calculate resistance and voltage drop maps to identify loss mechanisms and optimise contact geometry.
Virtually upscale devices from small prototypes to large modules to predict efficiency before fabrication.
Integrate with drift–diffusion solvers for material-level accuracy, including mobility, recombination, and trap state effects.
Model printing and coating non-uniformities by assigning spatially varying parameters.

By combining large-area electrical simulation with trap state analysis and optical modelling, OghmaNano allows researchers and engineers to understand performance trade-offs in scaled-up devices and identify design improvements before committing to costly manufacturing runs.

This large-area simulation module works seamlessly with:

Advanced optical modelling for light distribution and shading analysis.
2D/3D drift–diffusion modelling for charge transport physics.
Module-level performance simulation for real-world deployment scenarios.

Keywords for discoverability: large-area photovoltaics simulation, module-level electrical modelling, spatially resolved performance analysis, printed electronics simulation, solar panel equivalent circuit, shading loss modelling.
