The electrical current generated by the cell under test determines the correct model. The choices include the 1-amp or 10-amp models. To configure a complete test station, the cell holder size, solar simulator size, PVIV model and accessories can be interchanged for optimal test scenarios.

The PVIV software 91540 version 2.1 is a LabVIEW™ based I-V measurement software suite with an intuitive, easy to use interface compatible with Windows 10. The software displays the raw I-V curve and calculates a number of critical cell performance parameters including short circuit current (I_sc), current density (J_sc), open circuit voltage (V_oc), fill factor (ff), maximum output power (P_max), maximum output voltage (V_max), maximum output current (I_max), cell efficiency (η), shunt resistance 1 sun (R@I_sc), series resistance 1 sun (R@V_oc), shunt resistance dark IV (R_Shunt) and other standard photovoltaic cell parameters. Multiple IV measurement results can be viewed simultaneously with multiple data presentation formats for enhanced visualization. Moreover, the software enables users to organize measurement settings in "recipes" which can be easily saved and recalled.

We are proud to house and manage one of the few commercial photovoltaic and calibration test laboratories in the world. The Photovoltaic Calibration and Test Laboratory is accredited by A2LA to the ISO/IEC 17025 Standard, using state of the art equipment for measurements in accordance with ASTM E948 and E1021. The lab welcomes requests for prototype PV device performance measurements or PV reference cell calibrations. Flexible scheduling and rapid turnaround time ensure minimal downtime to time sensitive devices.
