Tools for Solar Cell Research
Fluxim provides tools for research and development of new solar cell technologies. Our customers in industry and at universities use our simulation and measurement tools to understand device physics and improve power conversion efficiency and lifetime.
Various solar cell technologies and materials can be investigated such as organic solar cells, hybrid or quantum dot solar cells, perovskite solar cells, CIGS and others.
Optimize Light Absorption and Light Scattering
Use the simulation software setfos to simulate light absorption in thin-films. The interference pattern of organic solar cells for example are calculated to optimize all layer thicknesses to get maximum absorption.
Light scattering structures are often used to enhance the absorption in thin-film solar cells. Our light scattering module allows to define scattering interfaces to simulate and optimize the absorption.
Simulate Charge Transport with Drift-Diffusion
Simulate the charge transport of solar cells with the drift-diffusion module of setfos. The simulation results help to understand the device physics of solar cells and thereby improve the performance.
Our software is applied to organic as well as perovskite solar cells and others. In combination with our measurement system (see below) the simulation software gets even more powerful by fitting automatically to measured results.
Opto-Electrical Characterization of Solar Cells
Our all in one measurement system Paios allows to perform a variety of experimental techniques on solar cells including IV, TPV, TPC, CELIV, impedance spectroscopy, capacitance-voltage, charge extraction and others. Everything is measure automatically after each other leading to highly consistent measurement results.
Paios contains techniques specially designed for the characterization of perovskite solar cells as for example voltage preconditioning and measurement of the IV-curve hysteresis.
Simulate the Upscaling of Solar Cells
Record efficiencies are normally achieved on small area devices of a few square millimeters. To scale-up solar cells to larger areas is a challenge as ohmic losses due to lateral current flow lower the efficiency.
The simulation software Laoss allows to simulate large area solar cells. It can be used for metal grid optimization or to study the monolithic interconnection of a solar module.
