University of Utah engineers have devised a new way to slice thin wafers of germanium for use in efficient solar power cells. They say the new method should lower the cost of such cells by reducing the waste and breakage of the brittle semiconductor.
The cost of Germanium substrates varies considerably from manufacturer to manufacturer. The cost of this material can be as high as $50,000 per kilo of Germanium. The material is used in many applications, including thermographic imaging solutions, commercial security, firefighting, industrial monitoring equipment, and mirrors for lasers.
