Titanium Dioxide Powder For Solar Cell Applications

Titanium dioxide powder is commonly used as a key ingredient in the manufacturing of dye-sensitized solar cells (DSSCs), also known as Grätzel cells. The powder is applied as a thin film onto the surface of the solar cell, where it acts as a photoanode that helps to absorb light and generate electricity. The use of titanium dioxide in DSSCs is favored due to its high electron mobility, low toxicity, and cost-effectiveness.

Uses:

TiO2 is used as a semiconductor material in the production of solar cells. It is an important component of the photoanode, which is the layer that absorbs sunlight and initiates the electron transfer process that generates electrical energy.

TiO2 is also used in the production of dye-sensitized solar cells (DSSC) and perovskite solar cells (PSC), which are newer and more efficient types of solar cells.

Features:

TiO2 is a white, odorless, and non-toxic powder that is insoluble in water and most organic solvents.

It has a high refractive index, which means it is able to scatter and reflect light efficiently.

TiO2 is also a good electrical insulator, making it suitable for use in the photoanode layer of solar cells.
