A high-precision inspection system used to evaluate solar cells and wafers through multiple imaging and analysis modes— Photoluminescence (PL), Electroluminescence (EL), Infrared (IR), and IV curve testing. It detects micro-cracks, defects, impurities, resistance issues, and electrical performance parameters. The PL can be used after each manufacturing process like raw wafer, diffusion, deposition and printing. Ensures accurate quality grading, process optimization, and reliable efficiency measurement for PV manufacturing and R&D applications. Can be configured in any combination of EL/PL/IV/IR with manual and auto loading/unloading feature.
