Thin Solar Concentrator Prototype
HyperSolar Inc., a solar cell
power output technology company, has completed a prototype design of its thin solar
concentrator. The company’s goal is to develop an inexpensive and thin solar
concentrator to replace expensive solar cells in conventional flat solar panels.
The initial prototype is designed to provide 300 percent light magnification, but
the company aims for at least 400 percent in its final commercial product. HyperSolar
said that when successfully commercialized, a concentrator delivering 400 percent
light magnification could reduce the number of cells in a solar panel by 75 percent,
dramatically lowering the cost per watt of solar electricity. The commercial version
of the concentrator is expected to be approximately 1 cm thick.
- 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.
