solar cellIV Testing Software:

1. IV characteristic curve

（1) Under illumination conditions, a single test (including forward voltage scan and reverse voltage scan)Record the IV characteristic curve of the photovoltaic cell and output various indicator parameters, including Voc (open circuit voltage), Isc (short-circuit current), Pmax, Vmaxp, Imaxp, Rs (series resistance), Rsh (parallel resistance), Jsc (short-circuit current density), FF (fill factor), and η (luminous efficiency). At the same time, the IV curve of the entire quadrant can be viewed;

（2) Under illumination conditions, multiple consecutive measurements (including forward voltage scan and reverse voltage scan)Record the current and multiple measurements of the photovoltaic cell's IV characteristic curve, and display real-time statistical data of each test result. The interval time between multiple measurements can be customized;

（3) Voltage scanning direction controlUsers can perform single or multiple forward or reverse scan voltage IV tests as needed, as well as single or multiple alternating forward and reverse voltage tests;

（4) In the dark state, measure the parallel resistance Rsh of the battery, including single measurement and multiple continuous measurements;

2. The calibration of the solar simulator uses standard photovoltaic cells to calibrate the intensity of the solar simulator;

3. Dark state testing measures the series resistance Rs to verify the characteristics of the battery sample;

4. Steady state (bias) testing at Vpmax ormustUnder bias voltage, measure the stability curves of efficiency η, current density Jsc, current I, and power point Pmax over time t;

5. MPPT tracking test scans forward or backward, always tracking and measuring the changes in Pmax power point over time; Simultaneously measure the time-varying curves of Vmpp, Impp, and η conversion efficiency corresponding to this condition;

6. Repeatability Test measures the attenuation curves of various parameters of solar cells over multiple measurements or over time;

7. Automatic or manual data saving function: CSV, TXT, RTF, and JPG screenshots.
