> SWCT® encompasses the electrical and mechanical connection of solar cells encapsulating them into
strings
> This patented technology allows very cost-effective and resource-friendly mass production of high-
performance, top-quality solar modules
>
SWCT® is fairly versatile as almost all cell and module types can be processed, including state-of-the-art
developments such as bifacial HJT glass/glass solar modules
› An overall increase in solar module output of about 2% is possible using SWCTⓇ versus Busbar
> SWCTⓇ addresses the most important technical requirements of cell connection: minimal shading of the
active cell surface and low electrical resistance
› Compared to conventional square busbar connections, the round, thin SWCT® wires reduce shading of
the solar cell by up to 20% due to their significantly smaller contact surface. The active surface of the
solar cell - the area that can absorb light and convert it into electrical energy - is thus considerably larger
> SWCTⓇ uses an innovative foil wire electrode that comprises up to 38 impeccably aligned wires to
connect solar cells. The electrodes are aligned in parallel and fixed in position by means of an
electrode foil resulting in a series-connected set of cells - a "string"
> The lower process temperature of SWCT® encapsulation also prevents thermal stress on the strings,
particularly important for HJT cells that react sensitively to temperatures over 200 degrees Celsius
> SWCT® benefits from a reduced silver consumption: Only 0.095g of the precious metal is required
for the metallization of a bifacial HJT cell with SWCT®. This reduces silver consumption by up to 66%,
and module material costs by 6%, compared to other technologies
> The winning combination of higher energy yield and lower production costs currently makes SWCTⓇ
currently a cost-efficient connection method for solar cells
