Flexible Adaption of the System to Types of Cells and Faults Being Tested

The construction of large-area photoelectric solar power plants requires the application of high-performance solar cells and modules of excellent quality. InfraTec's thermographic testing system PV-LIT allows testing of solar cells for various types of defects even in the manufacturing process. It is also possible to carry out a continuous quality control for serial productions in order to sort defective cells out at an early stage and, following, avoiding additional costs. According to the to-be-tested types of defects, PV-LIT provides the use of contact testing (DLIT) as well as non-contact testing (ILIT).
