Photonics.com
Jun 2010
BEDFORD, Mass., June 14, 2010 — Spire Corp., a solar company that provides capital equipment and turnkey production lines to manufacture photovoltaic (PV) cells and modules, announced that its wholly owned subsidiary, Spire Semiconductor LLC received a contract from the Missile Defense Agency (MDA) to develop high efficiency, multi-junction solar cells for space applications.

Currently, the company is developing a 42 percent efficient, 500 sun concentrator cell us a US Department of Energy’s National Renewable Energy Laboratory contract. The MDA award will help it to further establish its capabilities in the concentrator photovoltaic (CPV) cell technology for space and terrestrial solar cell applications.

Spire Semiconductor provides wafer epitaxy, foundry services and device fabrication for solar and other industries.

GLOSSARY
epitaxy
A well controlled thin films technique for growing films with good crystal structure in ultra high vacuum environments at very low deposition rates. Epitaxy methods are well known for the growing of single crystals in which chemical reactions produce thin layers of materials whose lattice structures are identical to that of the substrate on which they are deposited. Some examples are molecular beam epitaxy, liquid phase epitaxy and vapor phase epitaxy. Molecular beam epitaxy is also commonly...
wafer
A cross-sectional slice cut from an ingot of either single-crystal, fused, polycrystalline or amorphous material that has refined surfaces either lapped or polished. Wafers are used either as substrates for electronic device manufacturing or as optics. Typically, they are made of silicon, quartz, gallium arsenide or indium phosphide.
