Definitions
- the present invention relates to a carrier substrate intended to enter in particular into the constitution of a solar cell, and more particularly at a front electrode of a solar cell.
- the front electrode of a solar cell is that of the two electrodes which is crossed first by the light rays.
- the electrodes consist of transparent and conductive oxides (so-called TCO) such as, in particular, tin oxide doped with SnO 2: F fluorine, zinc oxide doped with aluminum ZnOiAl (called AZO), ITO (mixed tin and indium oxide).
- TCO transparent and conductive oxides
- AZO zinc oxide doped with aluminum ZnOiAl
- ITO mixed tin and indium oxide
- SnO 2 F is very stable at ambient humidity, it has the disadvantage of being reduced in the form of metallic tin when it is subjected to hydrogen plasma during the deposition operation.
- functional layers such as silicon or germanium layers.
- ITO layers have the same disadvantage.
- ZnO Al which is very stable under hydrogen plasma corrodes rapidly after the texturing step, under the effect of humidity which causes serious problems when storing the glass product.
- AZO it is known that, to be conductive, its layers must be in the crystallized state, which has the disadvantage of requiring either an annealing operation of the magnetron-deposited layers at ambient temperature, a constituent operation. an additional step increasing the cost of the operation, ie a high temperature deposit which makes the deposition process more complex and more expensive.
- TCOs such as AZO or ITO nanotexturing
- the object of the present invention is to propose a carrier substrate for a solar cell which makes it possible to avoid the abovementioned disadvantages and for which the electrode is able to perform its function of electrical conduction both in the entire visible spectrum and the near infrared, which, moreover, is insensitive to the hydrogen plasma as well as to the humidity of the ambient atmosphere, and whose constitution is such that it makes it possible to ensure a decoupling of the conduction function provided by the electrode other functions of it, giving the designer a greater freedom of choice in the materials used.
- the subject of the present invention is therefore a carrier substrate, comprising a substrate, in particular with a glass function, transparent at least in the visible and near-infrared domains and receiving a conductive electrode that is transparent at least in the visible and near-infrared domains.
