A German research team has developed a nondestructive, on-site method to quantify water ingress in photovoltaic modules using near-infrared absorption (NIRA) spectroscopy calibrated with Karl-Fischer titration (KFT). The approach enables precise measurement of absolute moisture content in sealed modules without disassembly, improving inspection, failure analysis, and lifetime prediction.A German research group has developed a novel, nondestructive method to quantify water ingress in solar modules on site. The technique uses near-infrared absorption (NIRA) spectroscopy calibrated against absolute ...Den vollständigen Artikel lesen ...
