Teamtechnik receives stringer order for HJT module line


Teamtechnik will supply its stringer technology to an innovative module manufacturer based in Catania, Sicily. The TT140 ECA stringer will be used to connect cells based on heterojunction (HJT) technology.

The system utilizes an adhesive technology, which reduces thermal and mechanical stress on the cells. The technology was developed in-house by teamtechnik, and involves applying an electrically conductive adhesive (ECA) to both sides of the cell using a screen printing technique. Light capturing ribbons are then positioned, ready to be connected to the string, and cured at a temperature of roughly 160ºC.

According to teamtechnik, the technology has been tested in various applications, and found to reduce stresses on sensitive HJT cells.

The manufacturer ordered an unspecified number of the machines, and financial details of the transaction have not been disclosed.

“With our innovative adhesive technology for HJT cells we aim to support our customer in advancing the technology transition rapidly, say teamtechnik Vice President Sales Sven Kramer, “and to contribute towards enabling the production of high-performance modules with the lowest possible levelized cost of electricity.”

The name of the company placing the order was not given, however it is likely to be Italian company Enel SpA, which has previously announced plans to invest €80 million to convert its amorphous silicon facility in Catania to produce HJT modules.
