In perovskite solar cells, phosphonic acid derivatives are often used to passivate surface defects on the perovskite layer or electron transport layer. By forming self-assembled monolayers, they create a protective barrier that reduces the ingress of moisture and oxygen, which are primary causes of perovskite degradation. This surface modification significantly enhances the long-term operational stability and efficiency of PSCs.

Q: Are phosphonic acid derivatives considered nanomaterials?

While phosphonic acid derivatives themselves are molecular compounds, their application often involves forming self-assembled monolayers (SAMs) or being incorporated into nanostructured materials. When used for surface modification at the nanoscale, or when they functionalize nanoparticles, they are integral to the field of nanomaterials and nanotechnology, enabling the precise engineering of surfaces and interfaces for various applications, including solar cells.

Q: What are the broader applications of phosphonic acid derivatives in industry?

Beyond solar cells, phosphonic acid derivatives have diverse industrial applications. They are widely used as effective corrosion inhibitors in metal protection, scale inhibitors in water treatment, and flame retardants. Their ability to functionalize surfaces also makes them valuable in catalysis, sensors, and even in biomedical fields like drug delivery and bone tissue engineering, showcasing their remarkable versatility.
