  • Dalsa Enters Solar Cell Inspection
Mar 2009
Dalsa Corp. of Waterloo, Ontario, has entered into the solar cell inspection market. The company deals in area scan, line scan and embedded processing for inspection in the flat-panel display industry, which are now being applied to solar cell inspection, resulting in high quality yet cost-effective inspection capabilities for the solar cell industry. Solar cell manufacturers are under pressure to drive down costs in order to achieve "grid parity," the point at which the cost of solar energy is roughly equivalent to the cost of conventional power distributed on electric grids. Analysts forecast that this may occur in 2011 as module prices continue to drop.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
solar cell
A device for converting sunlight into electrical energy, consisting of a sandwich of P-type and N-type semiconducting wafers. A photon with sufficient energy striking the cell can dislodge an electron from an atom near the interface of the two crystal types. Electrons released in this way, collected at an electrode, can constitute an electrical current.
