6 FAQs about [Solar cell quality test]
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.
Are there standardized quality assurance guidelines for solar cells?
Apart from internal individual contract provisions between suppliers and manufacturers, standardized quality assurance guidelines for solar cells do not exist. The lack of standards and individual customer needs means customized test equipment and test are needed. This is where materials testing experts come into play.
What is the purpose of a solar panel test?
Determines the electrical parameters of the solar panel (rated power, current, voltage etc.) Used for light soaking and pre-conditioning of the solar panels. Also for some indoor testing of the panels when the weather conditions do not allow to the test outside.
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.
How to choose a solar module?
Power output and module efficiency are probably the two most discussed specifications when choosing solar modules. Solar modules are measured at STC, Standard Test Conditions, to benchmark the standard performance specifications: Light irradiance of 1,000 W/m 2. Solar cell temperature of 25°C.
What is solar cell characterization?
The most fundamental of solar cell characterization techniques is the measurement of cell efficiency. Standardized testing allows the comparison of devices manufactured at different companies and laboratories with different technologies to be compared. Air mass 1.5 spectrum (AM1.5) for terrestrial cells and Air Mass 0 (AM0) for space cells.
