Technical FAQs 4

How to choose a corrosion-resistant material for a solar cell?

By choosing materials with high inherent corrosion resistance, the vulnerability of solar cell components to corrosion can be significantly reduced . For metallic components, selecting corrosion-resistant metals or alloys, such as stain-less steel or corrosion-resistant coatings, can enhance their longevity and performance.

Are c-Si solar cells corrosion prone?

Crystalline silicon (c-Si) solar cells, being the most com-monly used photovoltaic technology , are susceptible to corrosion resulting from exposure to environmental factors like moisture, temperature variations, and impurities.

How is corrosion characterized in solar cells?

Scanning electron microscopy (SEM) is another valuable tool for characterizing corrosion in solar cells. SEM provides high-resolution images of the surface morphology, allowing for detailed examination of corrosion features, including corrosion products, localized corrosion sites, and material degradation.

Are solar cells prone to corrosion?

Transparent conductive oxide (TCO) layers, commonly used in solar cells, can be prone to corrosion, impacting their conductivity and transparency [13, 14]. The integrity of encapsulation materials, which protect the solar cell from environmental exposure, is also crucial in prevent-ing moisture ingress and corrosion .
