Lock-in and pulsed thermography for solar cells testing

Popis výsledku v původním jazyce

Inspection of solar cells is an important part of their production process, because even their small defects can cause a significant drop of a whole photo-voltaic module performance. LED illuminated lock-in (LEDILIT) and flash-pulse (FPT) thermographic techniques were compared in this study. Lock-in methods are more commonly used for solar cells inspection. The aim of the study was to find out if the FPT is appropriate for an inspection of defects of multicrystalline solar cells. Experimental setup, inspection results and advantages/disadvantages of both methods are presented. It was confirmed that the LEDILIT produced more clear indications. The FPT was not so efficient, but it was much faster and could detect many of defects also indicated by LEDILIT. FPT also indicated inhomogeneities at a bottom layer of a cell, which were not connected with a photo-voltaic effect and which were not revealed by LEDILIT
