Higher solar cell efficiency with pre- and post-coating PL inspection

Photoluminescence (PL) inspection stimulates photon emission by illuminating cells with specific wavelengths, revealing critical information about material integrity and electrical properties. LUMI-Q Coating is a photoluminescence inspection system designed for pre- and post-coating inspection. It automatically detects all relevant defects that have a negative impact on cell efficiency. LUMI-Q Coating can be integrated into existing systems without any additional footprint.
