STRINGER TT 1400 ECA bonding technology

On April 25, 2020, the solar panel machines manufacturer of the solar cell string automatic assembly system, Teamtechnik, released its STRINGER TT 1400 ECA bonding technology suitable for solar panel production line of crystalline silicon solar cells in Changzhou, Jiangsu.

Thinning of solar wafers and batteries will become a trend in the next few years, leading to higher fragmentation rates. In addition, new high-efficiency batteries such as back-contact batteries will occupy more than 10% of the market share in the future. High-efficiency batteries are very sensitive to high temperatures, and ECA technology can effectively avoid this weakness.

The new solder tape can be applied to production, and you can also try the production of five main grid batteries.

STRINGER TT1400 ECA string welding machine has realized the bonding technology of solar cell string in industrial mass production. So far, this innovative connection technology can only be used for manual processes and very small production lines. "ECA" in the name of the automatic assembly system stands for "Electrically Conductive Adhesive".

Teamtechnik conducted a series of rigorous quality tests on the solar cell modules with bonded strings: temperature cycle test according to the relevant standards and humidity test required by the module certification standards. All tests have proved that the use of adhesive bonding technology in the production of high-performance modules is significant. potential.

The new high-performance string welding system operates at 1400 ticks per hour, can handle temperature-sensitive cells, such as heterojunction (HJT) solar cells, and enables high-efficiency solar cell connectors (such as the LCRTM series) to be used Automatic manufacturing of solar cell strings.
