STRONGSVILLE, OH – November 9, 2007 – Momentive Performance Materials Inc. recently launched a new product line of Pyrolytic Boron Nitride (PBN) crucibles, heaters and coatings to consider for the enhancement of the production of CIGS (copper, indium, gallium, selinide) solar cells. Compared to other ceramic materials, PBN potentially provides a higher level of chemical and thermal stability and a lower total cost of ownership. Due to the relatively low wetting of PBN by most molten metals, PBN typically withstands the high temperature and high-volume throughput demands of CIGS solar cell manufacturing with minimal deterioration. “We’re confident that our new Pyrolytic Boron Nitride products will deliver exceptional performance and longevity for CIGS solar cell manufacturers,” said John Mariner, heater systems product manager, Momentive Quartz and Ceramics. “With these new products, we’ve built upon the capabilities of materials long used in the demanding semiconductor manufacturing environment.” Pyrolytic Boron Nitride (PBN) is an anistropic, high-temperature ceramic that exhibits a unique combination of high electrical resistance and good thermal conductivity. This non-toxic, non-porous compound is exceptionally pure by virtue of the synthesis process (high temperature/low press chemical vapor deposition). It can be deposited or easily machined into a wide variety of shapes, including crucibles, boats, tubes, bottles and machined plate products. As coatings on graphite, it may help protect heaters and evaporation sources from the corrosive effect of molten metals. PBN’s directional thermal conductivity provides excellent “heat spreading” capability for improved temperature uniformity. The combination of high strength, good thermal conductivity and a low coefficient of thermal expansion make the materials extremely resistant to thermal shock.
