What is the 2024 New Generation Solar PV Tinning Machine for Cell

Solar PV Tinning Machine for Cells 2024 New Generation is a specialized solar PV ribbon wire rolling and Tin coating equipment designed for the production of solar photovoltaic cells. In order to ensure efficient electrical conductivity and longevity of solar panels, tin coatings are applied to copper ribbons connecting solar cells within modules using this machine.

What improvements have been made to our 2024 New Generation Solar PV Tinning Machine?

Warpage is a result of cooling of solar cell after soldering/stringing Ever thinner solar cells require ever lower YS (Rp0.2%)

5 year ago: 300μm thick Si solar cell => YS < 140MPa*

Today: 160 – 180μm thick Si solar cell => YS < 70MPa* / < 80MPa*

Tomorrow: trend to thinner Si solar cell => YS < 50MPa* * Rp0.21% measured using bare copper ribbon thickness (excl. solder coating)

Areas of Improvement:

1. Ensure input copper quality

2. Chose the right annealing and rolling techniques

3. Optimize transport systems on the tinning line

4. Optimize payoff on the stringer
