Comparative Analysis of Layer Thickness Measurement Methods for Photovoltaic Modules: A Comprehensive Study

Abstract

Layer Thickness Measurement Methods for Photovoltaic Modules

The image shows an optical setup that measures individual layers inside small single-cell photovoltaic test modules without contact. In the foreground, a 3D scan based on optical coherence tomography of a small section of the module is presented as a color map, clearly distinguishing individual layers such as the solar cell, grid fingers, busbars, and backsheet. More details can be found in article number 2400219 by Lukas Neumaier and co-workers.
