Solar container welding parameters

Is current density inadequate for a solar cell interface joining?

Such results indicate that current density at 360 A/mm 2 is inadequate for the present interface joining. As the current density rises up to 417 A/mm 2, the joining interface between the Ag foil and Au surface of GaAs solar cell forms an integrated welding area (Fig. 9 d).

Are pgrw joints a thermal fatigue property of GaAs solar cell?

In the present research, PGRW joints connecting Ag interconnector and front electrode of GaAs solar cell are firstly produced using various current densities to obtain an optimized parameter set for further investigation on thermal fatigue property.

What is a cold welding process?

The “cold” welding process CMT means outstanding results with all materials, an extremely stable arc, and precision process-control. What makes this possible is that compared to conventional MIG/MAG welding, this process really is “cold”. Or to put it more accurately, one that constantly alternates between hot and cold.

Is peak welding temperature lower than base materials?

Acquired results indicate that the peak welding temperature is lower than base materials, and serious residual stress and deformation are distributed at electrode center and edge, respectively. Y.

What is parallel gap resistance welding (pgrw)?

To date, due to high working efficiency and low cost, parallel gap resistance welding (PGRW) has become a widely used joining method for micro component , , , .

Which AG Interconnector is absorbed into a GaAs solar cell?

Ag interconnector, Au layer and Ag electrode of GaAs solar cell are clearly identified by bright field (BF) mode of TEM (Fig. 11 a). It is very clear that the Au layer is absorbed into Ag grain.
