Automated cell interconnection on industrial cell stringer for 3-5 busbars.
High-efficiency module concept using shingled cell interconnection.
In a PV module, solar cells are electrically connected to strings. The interconnection causes ohmic and optical losses in a module and affects the product reliability. In our Module Technology Center (Module-TEC) we use various soldering technologies and industrial stringing equipment for
- 3, 4 and 5 busbars
- Full- and half-sized cells
- Heterojunction cells
- Optically enhanced ribbons
- Multi-Wire interconnection
- Conductive adhesives
- Shingle interconnection
- Shaped ribbons and wires for back contact cells
- MWT cell interconnection through conductive backsheets
