Cell Cracking Invisible EL Testing: Find Hidden PV Damage

cell cracking invisible el testing

Cell cracking invisible EL testing uses electroluminescence imaging to reveal electrically inactive regions, silicon cracks, broken fingers, solder faults, and other photovoltaic defects hidden beneath glass and encapsulant. A controlled forward-bias current makes the silicon emit near-infrared light, while a filtered camera records dark interruptions in the emission pattern. Key Facts at a Glance What […]
