Photovoltaic Testing System
Solar power generation is a clean and inexhaustive power generation for the future and is growing quickly around the world.
I-V test is the most important test for Photovoltaic cell/module manufacturing because the measured power rating or efficiency of the cell or module directly affects the selling price of the product. Therefore, highly accurate and repeatable I-V test result is not only for quality issue but also for business issue.
Jmida Technology, LLC offers complete Photovoltaic cells I-V Testers and systems:
- Offers flexible current and voltage ranges.
- Provides measurement results to your database.
- Uses 4-wire connection to test device mounting and contacting fixtures.
- User friendly software.

Testing Software
Our Photovoltaic cells I-V Testers comes with free measuring and analyzing software. Users can set their testing conditions and control the tester scanning I-V curve.
The software measures and displays the following cell parameters:
- Complete I-V curve.
- Open circuit voltage, Voc.
- Short-circuit current, Isc.
- Cell temperature, in °C.
- Peak power, Pmax.
- Cell efficiency, η.
- Fill factor, FF.
- Series resistance, Rs.
- Shunt resistance, Rsh.
- Current Density.
The test result can be saved as database and txt format files. Users can export the result data to other software to process the data.
The I-V Tester can be ordered as a stand-alone system or integrated into any manufacturing or laboratory environment. Our engineers would like to work with you to ensure that the I-V Tester you choose is optimized for your application..
Solar Simulators and Test Fixtures
Solar simulators are essential tools of solar cell testing for manufacturing as well as R&D. Low cost, Class AAA, different power output and beam size Solar Simulators are available.
Test fixtures which hold and connect solar cell to the I-V tester are available. Jmida offers standard or customer designed I-V Test Fixtures, including simple hold down devices, front and rear side spring probe contact, two or three busbars with 4-wires Kelvin connection. The temperature controlled fixtures are also available.
