Application of Violet Tungsten Oxide in a New Thin Film Solar Cell

As a transition oxide of tungsten, violet tungsten oxide has a good catalytic effect in the electrode reaction of a novel thin-film solar cell. Due to the high efficiency and low cost of the violet tungsten oxide so that it can be used in a novel thin-film solar cell More extensive.

Tungsten is a versatile metal element that has four stable oxides under different conditions: yellow oxide, blue oxide, violet oxide and tan oxide. Violet tungsten oxide, abbreviated as VTO, is a kind of tungsten oxide and is a purple fine crushed crystal powder. The general use of violet tungsten oxide is mainly used for the production kind of tungsten metal powder and tungsten carbide.

With the development of the times and technology, violet tungsten oxide has been paid more and more attention as a new type of electrode catalyst in the research of chemical composition, morphology and surface structure of new thin film solar cells. The electrodes are usually made of Pt, Au and other precious metals In the new thin-film solar cells, while Pt, Au and other precious metals are expensive and have limited reserves, which will inevitably affect the mass production in the future. Therefore, new alternative Materials have become the main direction of current research.
