Solar Panel & Solar Cell Inspection

Manufacturing solar cells and solar panels involves the precise layering of materials including glass, semiconductors, metals, and antireflective coatings.

Subjecting them to many sophisticated etching, bonding and electrochemical processing steps is also part of the process. Yield is critical, and Photoluminescence optical inspection is an important tool to allow selection of highest efficiency wafers which will later be processed and built into panels.

Photoluminescence techniques can also be used with modulated light source / panel operation to carry inspection on installed panels during day light.
