Definitions
- the invention relates to a photo voltaic cell front face substrate, in particular a transparent glass substrate, and to a photovoltaic cell incorporating such a substrate.
- a photovoltaic photovoltaic material system that generates electrical energy under the effect of incident radiation is positioned between a back-face substrate and a front-face substrate, this front-face substrate being the first substrate which is traversed by the incident radiation before it reaches the photovoltaic material.
- the front-face substrate conventionally comprises, beneath a main surface facing the photovoltaic material, a transparent electrode coating in electrical contact with the photovoltaic material disposed below when considering that the main direction arrival of incident radiation is from above.
- This front face electrode coating is thus, in general, the negative terminal (or collecting the holes) of the solar cell.
- the solar cell also has on the backside substrate an electrode coating which then constitutes the positive (or collecting the electrons) terminal of the solar cell, but in general, the electrode coating of the backside substrate is not transparent.
- the material usually used for the transparent electrode coating of the front-face substrate is generally a transparent conductive oxide (“TCO”) material, such as for example an indium oxide-based material.
- the doping means for a mass fraction of less than 10 or based on fluorine-doped tin oxide ( SnO2: F), or in mixed oxide of zinc and indium (IZO).
- CVD chemical vapor deposition
- PECVD plasma
- magnetic field magnetic field
- the TCO-based electrode coating in order to achieve the desired electrical conduction, or rather the desired low resistance, the TCO-based electrode coating must be deposited at a relatively large physical thickness, in the range of 500 to 1000 nm and sometimes even more. expensive in terms of the price of these materials when deposited in thin layers.
- the transparent electrode coating consists of a stack of thin layers deposited on a main face of the front-face substrate, this coating comprising at least one less a TCO layer based on aluminum doped zinc oxide (ZnO: Al) or antimony doped tin oxide (SnO 2: Sb).
- the main disadvantage of this prior art lies in the fact that the materials are deposited at ambient temperature and by a magnetron sputtering technique and the layers thus obtained are of amorphous nature or less crystallized than the layers obtained by hot deposition, and therefore weakly or moderately electrically conductive. It is therefore necessary to subject them to a heat treatment, for example of the type annealing under a controlled atmosphere to increase the crystallinity of the layer, which also improves the light transmission.
- a heat treatment for example of the type annealing under a controlled atmosphere to increase the crystallinity of the layer, which also improves the light transmission.
- US20080047602 an electrode structure for a photovoltaic cell with silicon-based photovoltaic absorbing material for which it is necessary to add, above the transparent conductive layer based on zinc oxide, a layer of mixed oxide of tin, in order to facilitate the passage of the holes from silicon to silicon, so that the electrode has a higher output work.
- the main disadvantage of this prior art lies in the fact that the electrode is in fact made of 2 materials, which complicates the deposition process, and moreover, the second conductive oxide is ITO, is an expensive material and very little conducive to etching or texturing, this texturing phase being necessary for the operation of silicon-based photovoltaic cells.
- the present invention therefore aims to overcome the drawbacks of the solutions of the prior art by proposing a method of producing a transparent conductive electrode without adding an adaptation layer of the output work.
- An important object of the invention is to allow the charge transport between the electrode coating and the photo voltaic material, in particular based on silicon, to be easily controlled and that the efficiency of the cell can be consequently improved.
- the subject of the invention is thus a method for manufacturing a transparent electrode based on zinc oxide which is characterized in that it is deposited on at least one of the faces of a substrate or on at least one at least one layer in contact with one of the faces of said substrate, a layer based on zinc oxide, and in that this layer is subjected to a heat treatment so as to superoxidize a surface portion of said layer over a fraction of its thickness.
- the transparent conductive layer is based on zinc oxide, on-stoichiometric, optionally doped. Its physical thickness is preferably between 400 and
- the transparent conductive layer is optionally deposited, according to an alternative embodiment of the invention, on an anchoring layer, intended to promote the proper crystalline orientation.
- an anchoring layer intended to promote the proper crystalline orientation.
- this anchoring layer is in particular based on mixed zinc oxide and tin or based on mixed indium oxide and tin (ITO).
- the transparent conductive layer is deposited on a layer having a function of chemical barrier to diffusion, and in particular to the diffusion of sodium from the substrate, thus protecting the coating forming the electrode, and more particularly the conductive layer, especially during a possible heat treatment, in particular quenching, the physical thickness of this barrier layer is between 20 and 50 nm.
- the stack comprises a metal blocking layer capable of being oxidized during a heat treatment.
- the metal blocking layer is based on titanium, chromium, nickel, niobium, zinc, tin, used alone or as a mixture, and its thickness st is between 0.5 and 20 nm, preferably between 0.5 and 10. nm.
- the metal blocking layer is located below, or above or even above and below (the materials forming each of the blocking layers then being different), the electroconductive layer based on doped ZnO.
- this blocking layer Thanks to the presence of this blocking layer, it is possible to obtain, by a cold deposition process, identical performances to those obtained by hot deposition and the performances obtained after heat treatment are improved compared to to those obtained before heat treatment.
- the electrode coating must be transparent. It must thus have, deposited on the substrate, in the wavelength range between 300 and 1200 nm, a minimum average light transmission of 65%, or even 75% and more preferably 85% or more, in particular of at least 90%. If the front-face substrate is subjected to a heat treatment, in particular quenching, after the deposition of the thin layers and before its integration into the photo voltaic cell, it is quite possible that before the heat treatment the substrate coated with the stack acting as electrode coating is not very transparent. It may for example have, before this heat treatment a light transmission in the visible less than 65%, or even less than 50%.
- the electrode coating is transparent in the wavelength range between 300 and 1200 nm, a minimum average light transmission of 65% or even 75% and more preferably 85% or more, especially of at least 90%.
- the manufacturing process of the cell preferably requires an etching phase of the electrode in order to texturize the contact surface between the electrode and the silicon-based functional layer.
- the electrode obtained by the process according to the invention does not require an overcoating protection quenching, the latter can be textured without any difficulty by conventional techniques known to those skilled in the art (bath texturing). acid for example).
- the stack does not have in absolute the best light transmission possible, but has the best possible light transmission in the context of the photovoltaic cell according to the invention, that is to say that is to say in the quantum efficiency range QE of the photovoltaic material in question.
- the quantum efficiency QE is in a known manner the expression of the probability (between 0 and 1) that an incident photon with a wavelength according to the abscissa is transformed into an electron-hole pair .
- the maximum absorption wavelength ⁇ m that is to say the wavelength at which the quantum efficiency is maximum, is the order of 540 nm for amorphous silicon and of the order of 710 nm for microcrystalline silicon.
- the transparent conductive layer is preferably deposited in a crystallized form or in an amorphous form but which becomes crystallized after heat treatment, on a thin dielectric layer which (then called “anchoring layer” because promoting the proper crystalline orientation of the metal layer deposited thereon).
- the transparent conductive layer is thus preferably deposited over one or even directly onto an oxide-based anchor layer, in particular based on zinc oxide or on the basis of mixed zinc oxide. and tin, optionally doped, optionally with aluminum (the doping is understood in a usual way as exposing a presence of the element in an amount of 0.1 to 10 mol% of metal element in the layer and the term "base-based” refers in a usual manner to a layer containing predominantly the material, the expression "based on” thus covers the doping of this material by another), or base of zinc oxide and tin oxide, optionally doped one and / or the other.
- the physical thickness (or actual thickness) of the anchoring layer is preferably between 2 and 30 nm and more preferably between 3 and 20 nm.
- This anchoring layer is a material which preferably has a resistivity p equal to the product of the resistance per square of the layer by its thickness) such that 0.2 m ⁇ .cm ⁇ p ⁇ 200 ⁇ .cm.
- the stack is generally obtained by a succession of deposits made by a technique using the vacuum such as sputtering possibly assisted by magnetic field.
- the substrate may comprise a coating based on photo voltaic material, especially based on silicon (amorphous, ⁇ crystalline, tandem), above the electrode coating opposite the front face substrate.
- a preferred structure of front-face substrate according to the invention is thus of the type: substrate / electrode coating / photo voltaic material.
- All the layers of the electrode coating are preferably deposited by a vacuum deposition technique, but it is not excluded, however, that the first or the first layers of the stack may be deposited by a another technique, for example by a thermal decomposition technique of the pyrolysis or CVD type, optionally under vacuum.
- the electrode coating according to the invention can quite well be used as a backside electrode coating, in particular when it is desired that at least a small part of the incident radiation passes completely through the photovoltaic cell.
