OghmaNano
Simulate organic/Perovskite Solar Cells, OFETs, and OLEDs DOWNLOAD
📦 Solar Cell Simulation Software — Free OPV, Perovskite & More
OghmaNano is powerful solar cell simulation software for modelling a wide range of devices, including
perovskite solar cells,
silicon-based structures, and
large-area devices.
It supports organic photovoltaics (OPVs) in steady state, transient, and frequency domains with advanced physical realism.
The simulator goes far beyond equivalent circuits by solving full drift–diffusion equations combined with thin-film optical solvers,
allowing you to directly compare simulation with experiment — not just fit curves.
Main window — advanced 3D interface to efficiently simulate devices.
Advanced transfer matrix methods to simulate light propagation.
Light current–voltage curves.
Whether you're designing a tandem OPV, testing a new donor–acceptor pair, or interpreting PL/EL data, OghmaNano provides the flexibility and physical fidelity to guide your research.
🚀 What You Can Do with This Solar Cell Simulation Software
Build your stack: Quickly define donor, acceptor, interlayer, and electrode materials — all with spatially resolved properties.
Tune device physics: Control exciton diffusion length, carrier mobilities, bimolecular and trap-assisted recombination rates, and contact types.
Extract key parameters: Fit JV, CE, or TPV measurements to determine mobility, lifetime, recombination coefficients, and more.
Visualize internal physics: Explore electric fields, carrier densities, potential profiles, recombination maps, and quasi-Fermi levels in 1D, 2D, or 3D.
Model light management: Use optical models (e.g. transfer matrix or FDTD-based absorption) to predict generation profiles across multilayer stacks.
Simulate spectra: Predict photoluminescence (PL) and electroluminescence (EL) spectra from first principles using full carrier dynamics and emission rates.
Understand loss mechanisms: Identify where losses occur — such as contact resistance, trap states, or energetic disorder — and diagnose what limits your fill factor or open-circuit voltage.
Optimize without fabrication: Perform full device sweeps in silico before entering the lab — saving time, materials, and effort.
This solar cell simulation software includes a library of pre-built, calibrated device examples from the literature — including
bulk heterojunction (BHJ), planar heterojunction, and tandem OPV structures — so you can run, modify, and extend realistic models straight away.
Beyond OPV, you’ll also find example simulations for
perovskite solar cells,
silicon-based devices, and
large-area modules.
Load a P3HT:PCBM or PM6:Y6 device in 3D with realistic absorption, recombination, and contact models.
Edit material parameters or stack geometry via Lua scripts or the graphical doping editor.
Overlay your experimental data to compare and fine-tune models quickly.
🔧 Designed for Experimentalists and Modelers
Whether you’re a graduate student trying to interpret JV curves, or a device physicist building tandem stacks,
OghmaNano provides detailed insight into the internal workings of your devices.
It’s ideal for teaching, research, and prototyping — all for free.
