GaInP/Ga(In)As/Ge triple-junction solar cells are currently the most mature and widely used technology for concentration photovoltaic (CPV) applications and space power. These devices can degrade when operating under reverse bias, what could occur, for example, when a solar cell is totally or partially shaded.
Despite the solid analysis in the aforementioned published reviews [15,16,17,18,19], Another failure that solar cells might experience is through disconnection of solar cell busbars or ribbons. This type of failure occurs because of a manufacturing defect; it is also driven by excessive heat due to long partial shading and can produce

The risk priority analysis is considered one of the promising approaches for identifying the severity of failure modes. The study reports shows that the inverter and ground system has a failure mode with high RPN. Table 1 summarizes various faults related to solar PV systems as reported in the literature studied.

The failure of the components affects the reliability of solar PV systems. The published research on the FMEA of PV systems focuses on limited PV module faults, line-line contact faults, string faults, inverter faults, etc. The literature shows that the reliability analysis method is used to evaluate different faults in PV systems.
In terms of failure detection techniques, it was pointed out that these should be simple, applicable to most PV systems, cost-effective, accurate, and able to detect failures at low solar irradiance levels. Typically, detection starts with visual inspection and then employs more instrumental methods such as infrared imaging.
They found that the most common causes of early failure are junction box failure, glass breakage, defective cell interconnect, loose frame, and delamination. A study by DeGraaff on PV modules that had been in the field for at least 8 years estimated that around 2% of PV modules failed after 11–12 years.
This arti-cle demonstrates the possibilities of lock-in thermog-raphy (LIT) techniques for detailed failure analysis of solar cells. Lock-in thermography is well established for failure analysis application in integrated circuits (ICs).
Independent component analysis, fast Fourier transform, and principal component analysis algorithms are used for this purpose. This thermography approach enables detection of micro defects and other failures in solar cells that were not identified previously by thermography.
