Photovoltaic (PV) cell testing is an important part of PV semiconductor design and fabrication, and includes a variety of tests that help ensure the quality and efficiency of the product. Continuous or pulsed I-V testing is used to determine electrical performance parameters such as the short-circuit current, open-circuit voltage, operating power, and efficiency. Solar cell I-V characterization is vital for researchers and is also used during PV manufacturing to sort the PV cells for assembly into modules and arrays. Tests are also conducted to validate the presence of any opens and shorts to detect manufacturing defects that may contribute to decreased energy conversion efficiency.

Photovoltaic Solar Cell I-V Characterization Bundle
This bundle contains the software and hardware components required for photovoltaic solar cell characterization. With this system, you can perform forward-bias (illuminated) on photovoltaic cells up to 2A and 20V (add more SMUs to get three times the voltage or current) or reverse-bias (dark) tests.
- Continuous DC I-V characterization
- Sourcing and sinking capabilities for forward-bias and revers-bias tests
- Free downloadable forward-bias I-V analysis code

Pulsed I-V Test System for Photovoltaic Solar Cells
In a pulsed system, an external load is needed to direct the current/voltage sweep, and NI products are used to measure the pulsed current and voltage emitted from the solar cell during this process.
- Flexibility to choose hardware that matches system requirements
- Ideal for systems with high channel count, or where heat generation is a concern
- Free downloadable forward-bias I-V analysis code
