Eddy current soldering of solar cell ribbons under a layer of glass

In this research, we develop eddy current soldering as a non-contact soldering technique for tabbing the ribbon of PV cells under a layer of glass. The performance of eddy current soldering was studied in detail by changing an induction coil distance to the treated sample from 2 to 4 mm and varying exposure time.

6 FAQs about [Solar cells at different soldering temperatures]

How does soldering a solar panel affect temperature?

An aluminium back surface and already soldered ribbon at the negative side typically resulted in lower temperatures (5–15 °C) on the positive side. The difference was the highest at a 2 mm distance. Heating profiles at 2 mm and 3 mm distances overlapped, indicating repeatable soldering conditions and the uniform quality of the solar cells.

Is low-temperature soldering suitable for SHJ solar cells?

Since the passivation by the amorphous silicon layers of SHJ cells cannot withstand temperatures above 250 °C [7, 8], low-temperature soldering is considered as a suitable technology. The main challenge is to overcome the known weak adhesion between metallization paste and wafer surface, observed after soldering on SHJ solar cells .

Can solar cells be soldered?

Besides soldering, gluing of solar cells using electrically conductive adhesives (ECAs) can be used to create the electrical contact between the cell connector and the solar cell electrode .

Can solar cells be used to test metallization pastes after soldering?
