TiO2 paste is widely used in the production of dye-sensitized solar cells (DSSCs) due to its excellent photocatalytic properties and ability to absorb UV light. It serves as a key component in the photoanode, where it helps in the efficient conversion of sunlight into electrical energy. Additionally, TiO2 paste is utilized in the manufacturing of perovskite solar cells, enhancing their stability and performance.

In the field of cosmetics, TiO2 paste is incorporated into sunscreens and skincare products for its UV-blocking capabilities, providing protection against harmful ultraviolet rays. It is also employed in the formulation of paints and coatings, where it acts as a pigment and improves durability, opacity, and resistance to weathering.

Furthermore, TiO2 paste finds applications in environmental remediation, particularly in water and air purification systems. Its photocatalytic activity enables the breakdown of organic pollutants and harmful microorganisms, contributing to cleaner and safer environments. In the textile industry, it is used to create self-cleaning fabrics by leveraging its ability to decompose dirt and stains when exposed to light.

Overall, TiO2 paste is a versatile material with significant contributions to renewable energy, personal care, industrial coatings, and environmental sustainability.
