What is buried interface in a perovskite solar cell?

The buried interface in the perovskite solar cell (PSC) has been regarded as a breakthrough to boost the power conversion efficiency and stability. However, a comprehensive manipulation of the buried interface in terms of the transport layer, buried interlayer, and perovskite layer has been largely overlooked.

Are long-lived inverted perovskite solar cells prone to corrosion?

One big challenge for long-lived inverted perovskite solar cells (PSCs) is that commonly used metal electrodes react with perovskite layer, inducing electrode corrosion and device degradation.

Why should solar cells be protected from corrosion?

By implementing effective corrosion prevention and control strategies, the efficiency of solar cells can be enhanced by mitigating losses caused by corrosion-related factors. Additionally, the reliability and lifespan of solar cells can be extended, ensuring consistent performance over an extended period.

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

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 stainless steel or corrosion-resistant coatings, can enhance their longevity and performance.

How to protect c-Si solar cells from corrosion?

One approach to mitigate corrosion in c-Si solar cells is the application of protective coatings on metallic components, such as interconnects and contacts . These coatings act as a barrier, protecting the underlying materials from direct contact with moisture and corrosive substances.

What causes galvanic corrosion in solar cells?

In solar cells, galvanic corrosion can occur at the interface between different metals or between metals and conductive coatings . For instance, when metals like aluminum or steel are in contact with more noble metals such as silver or copper, galvanic corrosion can take place.
