6 FAQs about [Thermal imaging detection of hidden cracks in photovoltaic panels]

Can El imaging detect cracks in solar cells?

According to Fig. 9, a solar cell sample has been observed using EL imaging technique. As noticed, multiple cracks appear in the EL image, where in fact, the detection of the cracks have been improved using the proposed algorithm.

What is solar cell micro crack detection technique?

Solar cell micro crack detection technique is proposed. Conventional Electroluminescence (EL) is used to inspect the solar cell cracks. The techniques is based on a Binary and Discreet Fourier Transform (DFT) image processing models. Maximum detection and image refinement speed of 2.52s has been obtained.

What is the difference between solar cell cracking and PID?

Therefore, solar cell cracking and PID are different; however, both lead to a drop in the output power of the modules. Cracks are often invisible to the bare eye; the current standard cracks detection method uses Electroluminescence (EL) imaging 18, 19, 20. In Fig. 1, the EL image of two different solar cells is presented.

Can photoluminescence imaging detect cracked solar cells?

Our method is reliant on the detection of an EL image for cracked solar cell samples, while we did not use the Photoluminescence (PL) imaging technique as it is ideally used to inspect solar cells purity and crystalline quality for quantification of the amount of disorder to the purities in the materials.

How important is the detection of crack defects in solar cells?

Therefore, the detection of crack defects is very critical. Although the degree of automation and intelligence in today’s solar cell manufacturing process is already quite high, the detection of defects and the rejection of unqualified solar cells are still mostly done manually.

How to detect small cracks in PV modules?

Detecting small cracks in PV modules is a challenging task. These cracks can occur during production, installation and operation stages. Electroluminescence (EL) imaging test procedure is often used to detect these cracks. Defective images with linear and star cracks obtained from EL are collected.
