We use the fluorescence effect of the lamination material of photovoltaic (PV) modules to detect cracks in wafer-based solar cells in a power plant. For this purpose, the PV modules are irradiated by ultraviolet (UV) light, and the fluorescence light is measured by a camera. The measurement is realized in the dark. This new application of the fluorescence method allows new insight into cracks of a huge amount of PV modules during service life without remounting or touching the PV modules. We… CONTINUE READING
