3 FAQs about [Photovoltaic back-end EL calibration board]

How to obtain El images from PV modules?

In general, the forward bias current needs to be injected into the modules that cause EL emission at a wavelength of 1150 (Coello, 2011, Yongqing et al., 2013, Fuyuki et al., 2007) to obtain the EL images. A silicon Charge-coupled Device (CCD) sensor unit is adopted to capture the images in front of the PV modules (Köntges et al., 2014).

Is El inspection a good method for defect detection of PV cells?

Even though EL inspection needs some time and experienced specialists, it has become the main method for defect detection of PV cells due to its excellent performance. In this paper, an automatic method is proposed for solving the limits.

What is a primary reference cell calibration?

Interested in Primary Reference Cell Calibrations? Primary reference cells are calibrated for in-house use and for use by other national laboratories to provide clients and partners with a path for traceability to standards.
