Terrestrial Multi-Junction Solar Cells

SPECTROLAB DECLARES 37.8% EFFICIENT SOLAR CELLS

Terrestrial Multi-Junction Solar Cell

As technology has been revolutionised and getting advance day by day and one of the most important contemporary technology is the solar cells. It is a desire of every engineer to make environment green and they are trying every possible effort for the existence of such environment. One of the most famous Spectrolab that is a subsidiary of Boeing, known for the manufacturing of solar cells for spacecraft’s and satellites has now forwarding their attentions towards terrestrial solar cells for his name in the market of intensifying alternative energies. A California based company has claimed about efficiency of terrestrial multi-junction solar cells of about 37.8 percent without any need of solar focusing.

However Spectrolab and other companies have achieved high efficiency of solar cells by concentrating the rays of sun with help of mirrors on solar cells. The company said that they are able to produce such multi-junction solar cell with a high efficiency without any need of solar concentration.

The traditional solar cells are based on silicon technology whereas multi-junction solar cells contain different semiconductor materials that are interfaced with the help of a technique called p-n junction. Each material is tuned to specific wavelength of light to increase efficiency of solar cells.

It is not confirmed that which particular type of material is used in the multi-junction solar cell. It is just a news declared by the Boeing that an efficiency of 37.8 percent was achieved by using two or more materials in multi-junction solar cells. This will leverage the Boeing technology that manufactures semiconductor materials more trustworthy.  

The company said that we did not stop on our successes. Nasser Karam says that our company is able to produce high efficiencies of more than 45 percent under lower concentrations.
