Temperature monitoring of solar cells and semiconductors

In the solar and in the semiconductor industry, non-contact temperature measurement aids in the continuous monitoring of the production process and thus helps improving the production procedure. By detecting slightest changes in the thermal behaviour, possible malfunctions can be detected and solved easily and reliably. The thermal imagers of Optris are especially suited for these tasks. Thermal imagers are not the only option, though. Cost-effective alternatives can be found in our technical article Temperature monitoring of assembled circuit boards.

Quality control of solar cell modules

temperature measurements on solar cell moduls

Infrared cameras are essential instruments for the quality control of solar cells. One possibility of testing is the periodical modulated exposition of the solar cells to light (Illuminated Lock-In Thermography). The separation of charge within the solar cell leads to leakage current at defective parts and thus to local hot spots. The hot spots can be detected by the infrared camera.

Temperature monitoring of string soldering process

temperature monitoring during string soldering

For the production of solar modules the temperature of wafers is captured during the string soldering process. This assures a reliable and efficient assembling process. Temperature measurement takes place on the silicium surface which is connected to the braze point. That’s how the quality of the homogeneity of the soldering is measured.

Function tests of assembled circuit boards

PCB test through temperature measurement

More and more manufacturer of electronic components and circuit boards turn to the use of non-contact temperature measurement due to the increasing productivity of their components.  The thermal behaviour can be captured and optimised through the use of modern infrared measurement devices – without influencing the measuring object.
