6 FAQs about [Photovoltaic cell failure analysis pictures]

Can a cell crack be detected in a photovoltaic cell?

Using FL imaging, it is especially possible to detect cell cracks in cells of photovoltaic modules [Koentges12]. Cell cracks appear as a dark bar on the solar cell in the FL image. A cell crack is much easier to be identified than in an EL image. Due to the bleaching at the frame of regular cells, cracks at the cell edge are not detectable.

How to detect failures in PV modules?

There are basically three different types of thermography methods to detect failures in PV modules. The most common and easiest to apply technique is the thermography under steady state conditions. This method allows the analysis of PV modules in the field under working conditions.

What are typical failure scenarios for wafer-based crystalline photovoltaic modules?

Fig. 3.1: Three typical failure scenarios for wafer-based crystalline photovoltaic modules are shown. Definition of the used abbreviations: LID – light-induced degradation, PID – potential induced degradation, EVA – ethylene vinyl acetate, j-box – junction box. Infant-mortality failures occur in the beginning of the working life of a PV module.

Can electroluminescence detect cell cracks in photovoltaic modules?

Table 5.4.1 summarizes all effects being detectable with electroluminescence for wafer-based PV modules. The table 5.4.1 also shows the influence of the effects to the electrical parameters of a PV module. Using EL imaging, it is especially possible to detect cell cracks in photovoltaic modules.

What are the most common PV modules failures?

The most common PV modules are made of wafer-based silicon solar cells. Therefore a large knowledge base has been accumulated for the most PV module failures of this type. However even for this type of PV modules some effects like potential induced degradation and snail tracks have been studied in detail in the last 3 years for the first time.

What does a failure type mean in a PV module?

This failure type typically indicates a high strain at the solder joint. PV modules with this kind of failure typically show more of this failure after thermomechanical stress and lead e.g. to a higher power loss in the TC200 test than PV modules without this failure type [Wendt09].
