Five Perovskite Questions Setfos Can Answer From Your Own Measurements
Perovskite papers often describe a result without explaining it. Non-radiative recombination. Hysteresis artifact. Retained 90% of PCE. Five questions where fitting a physical model to your own data identifies the mechanism.
Setfos modeling of halide perovskite solar cells with focus on their mixed ionic-electronic conducting properties: a step-by-step tutorial
Learn how to create a realistic digital twin of a halide perovskite solar cell using Fluxim’s Setfos. This step-by-step guide explains how to combine Paios measurements with drift-diffusion and optical modeling to capture ionic migration, hysteresis, and impedance behavior—helping researchers link device physics to performance and stability.
Investigating Current Matching and Hysteresis in Perovskite-Silicon Tandem Solar Cells with Drift-Diffusion Simulations
Perovskite-silicon tandem solar cells are revolutionizing photovoltaics, but optimizing current matching between layers is critical for achieving peak efficiency. A mismatch can lead to power losses, limiting overall performance. In this blog, we explore how optical and electrical simulations help fine-tune device design, ensuring both sub-cells generate maximum power.
Discover how precise modeling can boost tandem cell efficiency and accelerate the path to commercialization.
Why Perovskite Solar cells with High Efficiency Show Small iV-curve Hysteresis
In many perovskite solar cells, hysteresis is observed between the forward and reverse current-voltage (IV) scans. This IV curve hysteresis can be problematic for the correct determination of the Power Conversion Efficiency (PCE). While the exact origin of the IV curve hysteresis has remained a topic of debate, it is now widely accepted that mobile ions are the principal cause. However, it is still the subject of ongoing debates about how exactly mobile ions influence the device operation.
In this blog, we are showing how a proper drift-diffusion simulation can help in understanding how mobile ions are affecting the JV characteristics of a perovskite solar cell.
