Designed for solar modules with cells for rear-side contacting, ‘AKACON BCF’ PV backsheet is being offered by the KREMPEL Group and is ready for volume production. The backsheet comes with a copper layer and is structured according to customer's design for back-contact cells.
The contacts are only located on the cell rear side. This means that space on the front is freed up so that cell output can be increased. Corresponding cell designs are available, as well as economically efficient process concepts and production lines. However, the new technology is still on the sensitive threshold between a promising concept and a marketable product.
The new AKACON BCF (Back Contacting Foil) family of products has everything that is essential for rear-side contacting: highly conductive contact surfaces on the cell side and excellent electrical insulation on the outward facing side. At the same time, the new product is said to reliably perform all the other functions of a classic PV backsheet laminate such as lasting protection against harmful environmental influences.
PV backsheet material is specifically designed for copper-based back-contact solar cell module lamination.
AKACON BCF offers outstanding flatness and high dimensional stability; the thermal shrinkage is less than 0.1 percent.
March 2013 onwards.
