4 FAQs about The solar module cell el turns black

How does a solar module work?

Photovoltaic (PV) modules are devices designed to transform sunlight into electricity. However, they can also work in the same way as a LED: By applying a polarization current, the solar module can be electrically stimulated to emit electroluminescence (EL) radiation.

Why are my solar panels underperforming?

The long-term performance of your solar panels depends on many factors. One of the most devastating causes of PV underperformance is also invisible to the naked eye: microcracks within the silicon cells that make up your solar modules. Microcracks are a type of defect that cannot be detected with visual inspection alone.

What is an El image in a solar cell?

An EL image allows a view inside the solar cell. It makes visible what is invisible from the outside. EL is thus somewhat comparable to an X-ray image. What defects can be seen in EL images? EL radiation emanates from the individual solar cells, meaning defects in the cell itself, as well as some defects in the wafer, can be identified.

Why do solar panels need electroluminescence testing?

You want every solar panel to be good before it leaves the factory. Electroluminescence testing helps you find hidden problems while making panels. You can see micro-cracks and other defects early. This stops you from sending out bad panels. You check for issues when making cells and building the whole module.
