Resistivity Measurement

This add-on option to thin film module inspection measures the sheet resistance of the solar panel's substrate coating. For an optimized panel efficiency, the conductivity of the coating layer should be at a maximum even at a low layer thickness.

As a helpful add-on to solar module inspection, Dr. Schenk offers a high sensitive sensor, that performs a non-contact measurement of the resistivity. This in-line measurement is making use of the Eddy current principle. In its down-web
movement along the line, the coated solar glass passes through the sensor's magnetic field of the coil of a high-frequency circuit.

The sensor is connected with the SolarInspect system and its analysis software, the visualization terminal will report a visual alarm, as soon as the preset recipe parameters are exceeded.
