The large, quickly evolving PV production market demands for a permanent improvement of the quality and reliability of PV modules. In recent years electroluminescence (EL), photoluminescence (PL) and infrared measurements (IR) demonstrated to be powerful, non-destructive tools for qualitative analysis of PV module performances. In previous works it was shown that for a fast detection with high resolution of the most common defects in PV modules, a combination of EL and IR measurements is necessary [1, 2, 3]. In spite of the number of available analyzing techniques, many failure and degradation mechanisms are still unknown. Therefore, the aim of this work was to improve the quality and reliability of PV modules by a more precise defect detection, the “defect tracking method”. The “defect tracking method” started with the analysis of crystalline cells and ended with the characterization of crystalline PV-modules which were produced from these cells.
