Definitions
- Metal-containing composition process for the production of electrical contact structures on electronic components and electronic component
- the present invention relates to a metal-containing composition, a method for producing electrical contact structures on electronic components and an electronic component provided with such a contacting.
- Silicon solar cells usually have metallic contacts both on the front side and on the rear side. Especially the contacts on the front have to fulfill several tasks and therefore make high demands on the contacting method and also on the contact material system.
- InkJet printing aerosol printing, pad printing or fine line screen printing can be realized.
- a metal layer is applied which is optimized to have a very good electrical conductivity and, in turn, to be readily contactable.
- the glass frit melts and wets the antireflection layer
- temperatures of about 750 0 C penetrates the glass melt in which at this temperature also silver is dissolved, the anti-reflective layer and penetrates further into the silicon
- the dissolved silver is precipitated from the melt and crystallizes directly on the silicon surface in the form of small silver crystallites.
- the cooled glass forms an insulating barrier between the volume silver of the finger and the silver crystallites, which in some places is thin enough is so that a current can flow from the cell into the contacts.
- This second metal layer can be realized, for example, by galvanic reinforcement of the first layer or by printing further, particularly good conductive metal layers on the first contact layer.
- Silver about 2 to 5 wt .-% of a glass frit and from 20 to 40 wt .-% of an organic vehicle system, via which the rheology of the ink / paste is set.
- the contacts insofar as they are realized in a single printing step, e.g. Screen printing, typically have a coating height of about 15 microns and a width of 120 microns. This means that in this case a much larger contact surface is available and therefore the requirements for the contact properties of the paste can be lower. In addition, it is known that the specific contact properties deteriorate with reduced metal layer height.
- compositions for making contacts by firing are known from various references, eg US 6,036,889, US 2004/0151893, US 2006/0102228, US 4,153,907 and US 6,814,795. All known formulations have an increased contact became common when thin contact structures were used on low-doped emitters.

- the composition according to the invention is, for example, a combination of silver and glass or low-melting oxide and a "pure" refractory oxide, thus a combination of silver and oxides, the proportion of oxide being comparatively high and the silver content being comparatively low Oxides and silver may also be known to the art MOD (organometallic decomposition materials). It is particularly advantageous in this case that a material system with a reduced proportion of silver also means a reduction in the cost of production. Moreover, it is possible for the first time with the present invention to contact solar cells with a high-impedance emitter and thus a high efficiency potential, with narrow, low-resistance contacts.
- contact widths of at least 80 microns are necessary to contact emitters with a sheet resistance> 100 ohms / square low impedance p c ⁇ 10 mOhmcm 2 .
- emitters> 100 ohms / square with contacts ⁇ 20 microns with a specific contact resistance p c ⁇ 2 mOhmcm 2 are contacted.
