Electroluminescence (EL) inspection is one of the key technologies for evaluating the quality of photovoltaic (PV) modules. By capturing near-infrared light emitted by solar cells under electrical
View Details
EL testing operates by stimulating solar cells with electrical current, causing them to emit infrared light. High-sensitivity cameras capture these emissions, generating detailed thermal maps
