6 FAQs about [Solar cell test binning]
How to test bifacial solar cells during production?
Abstract: Bifacial solar cells are becoming more common, but questions remain about how to effectively test them during production. IEC standards describe two equivalent methods for testing. We propose a measurement technique based on the equivalent intensity method, where bifacial cells are only illuminated on one side.
How do you test a solar cell?
A Kelvin or four-wire measurement is essential to getting accurate IV data while testing a solar cell. A variable load is applied across the four wires in order to get a variety of current and voltage measurements for the device under test. Exactly what current and voltage is unknown until tested, which is why there is some iteration needed.
What is a binning program?
Programs simulate the performance of modules with 36 series-connected cells and allow the division lines between bins to be adjusted until the desired results are obtained. These methods are valuable in keeping the binning scheme optimized in an industrial setting where cell performance improves over time. Content may be subject to copyright.
Why is a four-wire measurement important in a solar cell test?
The relationship between the two might need to be adjusted for the resistances of the wires, as in the example we described above, but overall the four-wire measurement is a way to accurately get current and voltage information of a device. A Kelvin or four-wire measurement is essential to getting accurate IV data while testing a solar cell.
