Abstract

Solar photovoltaic modules are versatile power sources that come in diverse materials and configurations, including compact

and flexible variants for portable electronic devices. Ensuring the reliability of these modules is crucial for sustaining the

functionality of the devices they power. Manufacturing or handling-induced defects, such as cracks or scratches, pose a threat

to the performance of solar modules. Hence, non-destructive inspection becomes essential in the quality control process.

Ultrasonic c-scan has been an established inspection technique within various industries, however, its application on solar

module remains uncommon. On the other hand, Scanning Acoustic Microscopy (SAM) has been implemented for observing

defects on solar cell, yet employing SAM for comprehensive module scanning is inefficient. This study aims to assess the

capability of ultrasonic c-scan in detecting micro-cracks within semi-flexible solar panels and to evaluate the effects of

frequency selection on the results. In this work, the specimen is investigated with an Ultrasonic C-Scanner at different

frequencies. Subsequently, the outcomes are validated by comparing them with the results from the SAM. The potential of

using a widely known ultrasonic technique, such as c-scan, for this purpose will enable a more straightforward integration of

the technique into the solar module quality control process.
