Abstract

This paper deals with the development of a differential eddy-current sensor probe working at various frequencies and used for analyzing the quality of solder joints of photovoltaic (PV) modules or cells. Due to environmental impacts, stress through thermal cycles and variable load conditions, solder joints of the cell connectors inside the PV module suffer and degrade or even in worst case completely fail. With the presented approach, the conductivity of each solder joint can be individually analyzed, enabling the possibility of early failure detection, in-line or even in the field. The measurement results prove that the evaluated condition correlate to the conductivity decrease of solder joints, which can be confirmed by electroluminescence (EL) images of a solar cell. This work bases on a previously executed investigation and depicts the next step in the further development of eddy-current testing within PV applications.
