BASF Exhibits at 25th EU PVSEC

From Sept. 6-9, 2010, BASF will exhibit at the 25th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC), presenting a range of innovative products for the solar industry. This year’s conference and exhibition, among the most important events in the global solar and photovoltaic industry, will be taking place in Valencia, Spain.

Experts will be on hand at BASF’s booth (D16 in hall L2 H4) to inform visitors about the company’s extensive offering, which covers the entire value-added chain for solar cells. Established products will be joined by two innovations: SELURIS Clean, an innovative and eco-friendly cleaning fluid; and a highly stable variant of BASF’s Ultramid plastic, ideal for manufacturing connectors and junction boxes.

SELURIS offers solutions for etching, texturizing, doping and cleaning mono- and polycrystalline solar cells. The range is now enhanced by the innovative eco-friendly cleaning fluid SELURIS Clean. Used before and after doping with phosphoric acid, SELURIS Clean enables more efficient hydrophilization and passivation of the solar cell wafers. This in turn achieves excellent wetting and even distribution of the phosphoric acid on the wafer, thus optimizing cell performance. SELURIS Clean can also be used at lower temperatures, which reduces manufacturing costs.

To efficiently use energy generated by photovoltaic plants, connectors are required. They transport the electricity to the end consumer. BASF supplies connectors and junction boxes made of a special variant of Ultramid. This plastic is highly stable, flame-retardant and low-temperature impact resistant, essential for the durability of plants exposed to the elements. Significant fluctuations in temperature and humidity also place high demands on the plastic components.

In addition to its new products, BASF will also show-case its well-established Pluriol series, a range of tailor-made wafer cutting fluids.

BASF will once again be presenting CypoSol and COLO-Fast. CypoSol is a range of silver and aluminum inks and pastes for the metallization of solar wafers. In addition to pastes for conventional screen printing, the CypoSol range also includes the L series, especially designed inks for the new laser transfer printing process. The lead-free inks are eco-friendly and can be used to print the front and backside of the wafer.

The polyurethane casting system COLO-Fast is a quick, economical and reliable method for framing photovoltaic panels and solar panels. The UV-stable PU system is able to replace traditional aluminum frames and opens up a variety of possible frame designs for the customer.
