Dr. Schenk SolarMeasure

Product Briefing Outline:

The Electrical Insulation Tester is a measurement solution for thin film solar modules. It performs an electrical insulation test between the solar cells after scribing. The system detects shorts and minimum resistance between neighboring cells.

Problem:

In thin film PV modules the electric current is flowing between the solar cells which are defined during laser scribing processes on the conductive layer (e.g. TCO or molybdenum). A discontinuity of these scribes will cause short circuits and minimum resistance between neighboring cells. Both situations can result in a loss of cell performance and by this in an overall reduction of the performance of the solar module.

Solution:

Dr. Schenk offers all-in-one quality assurance and process control systems for the solar panel production. The surface inspection systems SolarInspect can now be combined with beneficial measurement tasks in just one solution for higher yield.

With the Electrical Insulation Tester from the product line SolarMeasure,  shorts and minimum resistance between cells can reliably be detected. Modules with reduced performance quality can thus be rejected from further processing. At the same time, the system helps to draw conclusions, where parameters of the scribing process need adjustment.

Applications:

Dr. Schenk’s Electrical Insulation Tester is applicable to thin film solar modules with a wide range of dimension and thickness and is installed in-line after the P1 scribing.

Platform:

The Electrical Insulation Tester from Dr. Schenk is the ideal endorsement to surface inspection. The system is available as add-on to Dr. Schenk inspection systems SolarInspect or as stand-alone product.

Availability:

The Electrical Insulation tester from the SolarMeasure product family is available since Q3 2008 worldwide
