FT-IV2 I-V Curve Tracer: High-Precision IV Characteristic Analysis for Photovoltaic & Semiconductor Components

FT-IV2 I-V Curve Tracer is a high-precision testing equipment based on current-voltage (IV) characteristic analysis, used for performance evaluation of electronic components such as photovoltaic modules and semiconductor devices.

Working Principle

The working principle of FT-IV2 is based on the photoelectric effect and circuit measurement principles. Before testing, ensure the tested electronic component is correctly connected to the detector, and set simulated lighting conditions to replicate the light intensity and spectral distribution of the actual working environment. The component is first placed in an open-circuit state to measure its open-circuit voltage (Voc). The detector gradually increases the working voltage from 0V while precisely measuring the corresponding output current. By continuously measuring current responses at different voltages, a large number of voltage and current data points are obtained, thereby plotting a complete and accurate IV characteristic curve. This curve intuitively shows the current changes of the component at different voltages, reflecting core performance parameters such as photoelectric conversion efficiency, fill factor, and maximum power point.
