BASF Presents Photovoltaic Products at 27th EU PVSEC

BASF will be presenting its innovative products for the solar industry at the European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC) from Sept. 24-28, 2012. Visitors to Booth E 21 in Hall 3.0 at the Messe Frankfurt exhibition center can learn about the wide range of products for every link in the solar cell value chain.

BASF’s photovoltaic products include innovative plastics such as Ultramid for solar panels, plugs and sockets; chemicals for cleaning solar cells such as eco-friendly SELURIS Clean; plastics additives like Uvinul and Irganox; metallization inks and pastes (CypoSol); and the COLO-FAST polyurethane spray system for framing photovoltaic modules.

BASF plastic additives enable all plastics used in PV modules to withstand exposure to heat (Irgafos, Irganox) and sunlight (Chimassorb, Tinuvin, Uvinul). All over the world the company offers a broad range of heat and UV stabilizers for plastics. They are tailor-made for the various plastic resins used in PV applications like encapsulants, frames, backsheet films and electrical components to meet the lifetime requirements of at least 25 years.

CypoSol L is BASF’s range of special silver and aluminum inks designed specifically for the chemical company’s innovative laser transfer printing (LTP) process. Unlike conventional screen printing, LTP provides a contact-free way to print circuits onto solar cell wafers. The new printer not only boosts the efficiency of solar cell production, but also enhances cell performance. BASF initiated the development of this new printing process at Aurentum Innovationstechnologien GmbH.

CypoSol L inks are very eco-friendly and available in lead-free versions and as water-based solvents. They can be used for printing the front and rear sides of the solar cells. In addition to products for the LTP process, BASF also offers pastes for conventional screen printing in its CypoSol S line of products.
