Electroluminescence Solar Panel

Strengths of the electroluminescence test for solar panels are among others the accuracy and flexibility allowed by this technology.

Electroluminescence solar panel.

The high resolution offered by the cameras ensures a targeted and at the same time fast control which optimizes the performance of the line in terms of quality and efficiency. The light output increases with the local voltage so that regions with poor contact show up as dark. Prior to recombination electrons and holes may be separated either by doping the material to form a p n junction in semiconductor electroluminescent devices such as light emitting diodes or through excitation. At the same time many small and medium sized manufacturers do no invest.

The key advantage as noted above is the ability of electroluminescence imaging an entire solar cell or module in a relatively short space of time. Get it as soon as fri oct 2. A3 size electroluminescent el panel backlight sheet 12v 11 7 x 16 5. Ai driven el imaging software.

Electroluminescence is the result of radiative recombination of electrons holes in a material usually a semiconductor the excited electrons release their energy as photons light. Perform electroluminescence el testing on 100 of your solar modules on site at the pv factories in asia.

Solar manufacturing equipment pv module testing el inspection mondragon assembly provides systems for all types of applications from manual laboratory systems to fully automatic online solutions adapting the characteristics of these to each client s needs. Below a video scanning a swir camera across a panel of solar cells shows a large variation in el emission both within individual cells and across. Raptor photonics has published an application note explaining how its swir short wave infrared cameras can be used in drone based electroluminescence el imaging of photovoltaic pv solar panels. Nowadays the majority of large solar panel manufacturers have integrated the elcd test in their production lines.

With the help of an elcd test a pv manufacturer can evaluate the quality of the cells manufactured and any other possible defects caused by bad cell quality and or later mishandling of photovoltaic panels. This imaging process provides detailed high accuracy detection of defects and faults in the panels such as cracks broken cells interconnections and shunts.
