Solar Energy - Wafers


Credit: Eberhard Bamberg

Wafer of the element germanium, a semiconductor that is used in solar power cells.

Germanium wafers are expensive so maximum use of the material is a key factor. So far it is mainly spacecrafts that use this material, but with a new cutting technique that economize the production of these solar cells, we might get to use them here on Earth as well.
