So far, flexible films with transparent conductive oxidation of indium tin (ITO)
A wide range of applications have been studied due to its low resistivity (≤10u2009Ωu2009·u2009cm)
High transparency (≥80%)
In the visible area.
However, indium is very expensive (
Because of its scarcity.
Therefore, it is important to develop cheap materials with good photoelectric properties
Some potential alternatives, such as zinc oxide doping (ZnO)
And tin oxide (SnO)
It is considered as a promising alternative to flexible transparent conductive ITO film.
Unfortunately, the resistivity is still not low enough for practical applications.
The performance of flexible transparent conductive film is challenging due to trade reasons
Turn off between the treatment temperature and the performance of the film.
Recently, some researchers have tried to solve this problem by using a new structure.
Sandwich structure of dielectric/metal/dielectric multi-layer system.
This structure has flexibility, low resistivity and high transparency due to reflection from the metal layer, can be suppressed by multi-layer systems and achieve higher transparency.
In metal, gold (Au), silver (Ag)and cuprum (Cu)
Because they have very low resistivity.
But Al is more sensitive to oxygen than Ag and Au is more expensive.
So we chose Ag as the metal layer.

In the process of preparing transparent conductive film, due to its low cost, good adhesion, high deposition rate and friendly environment, it is considered to be the most favorable deposition method with uniform thickness in a large area, the deposition process is easy to control.
