TECC-Wire is a low-temperature (< 200°C) non-soldering solar cell inter-connection technology. Basically, a multi-wire approach with very special wires. We see a very good electrical and mechanical contact both to SiN and TCO. The observed losses can be attributed to the fully manual application of the wires.
The wire contacts under study are intended for use in silicon solar cells, most of which generate photocurrents of ⩽40 mA/cm 2 under standard solar illumination conditions (AM1.5G, 1000 W/m 2 ). The number of wire contacts in a solar cell is typically four to five per centimeter.
In the solar cell under consideration, solder must fill the space between the round wire and the substrate and form a contact strip, whose width should be close to the wire diameter. The wires were bonded by a lamination film to the TCO layer as well as to the contact pads using low-temperature (∼160 °C) lamination.
Perpendicular to the "busbars" are thinner metal "fingers" that collect the generated current and deliver it to the "busbars". The cost of metallization for the production of heterojunction solar cells has been significantly reduced by applying the "SmartWire" contact grid design . This design replaces the busbars with a lot of thin wires. ...
Conclusion The TECC-Wire technology has already shown its potential as a solder-free interconnection method for solar cells [, , , 17]. In this study, thermoplastic wire coating formulations with low Ag volume fractions were developed.
The SmartWire Contacting Technology (SWCT) consists of copper wires supported by a polymer foil (see Figure 1) [1, 2]. The wires are coated with a thin low melting point alloy layer, which melts during the module lamination process and builds up a solder contact to the cell metallization. This approach was initially proposed by Day4 Energy .
The number of wire contacts in a solar cell is typically four to five per centimeter. Therefore, the current per centimeter of the wire/TCO contact does not exceed ∼10 mA. Because of this, since the wire contact length in our test structures was 0.5 cm, the current in our I–V measurements was varied from −5 to +5 mA.

The larger the contact work function difference, the more improved the solar cell characteristics. Large work function differences may also avoid need for any doping in axial p-i-n nanowire solar cells. Saturation in I SC as well as degradation in current density with length can be minimized by spreading the contacts along the length of the ...
