Schott Solar reduces cost and silicon needs with new cell coating

From Schott Solar, a German solar cell manufacture, has developed a new coating for its solar cells that increase the efficiency of its cells while also reducing the amount of silicon used. While the numbers are hardly earthshattering in that the efficiency increase is .3-.5% and the reduction in silicon is 5% per watt, the bottom line is that this reduces the final cost of their solar panels, which is always welcome news.

Schott’s new process involves coating its solar cells with a surface called ISO Texture, which “roughens” the surface and increases the surface while reducing the reflection. While solar modules with the Schott ISO Texture can be bought in Germany, they won’t be available in the US market until Schott finishes its new manufacturing facility in 2009.
