Gallery: Boeing Planning Large Scale Production of Ultra Solar Cells

 

Best known for their massive jet planes, powerhouse Boeing is set to begin the large-scale production of their highly efficient concentrator photovoltaic cell (CPV), the C3MJ+. The cell is said to be one of the highest efficiency cells on the market today, with an average conversion efficiency of 39.2 percent. The cells, produced by Boeing subsidiary Spectrolab, will be a major improvement on the C3MJ cells currently in production, which can convert 38.5 percent of the sun’s rays into electricity.

Spectrolab is a market leader when it comes to the production of solar cells and photovoltaic technology, and has been producing such elements for various space and terrestrial applications for 50 years. Since 2007, the company has been introducing the large-scale production of solar cells that have consistently boasted an increased energy-conversion efficiency rate year on year.

The researchers at Spectrolab have even set a world record for solar cell efficiency with a test prototype that peaked at 41.6% – it has been said to be the basis for the solar cell C3MJ+ technology.

Speaking about the new cells, Russ Jones, Spectrolab director of CPV Business Development stated, “Given the new cells’ close similarity to our existing production cells, we believe that our current C3MJ customers will be able to easily upgrade for more efficiency.”

The important difference between concentrator photovoltaic cells and conventional PV cells is the multi-layer structure of semiconductor material aimed at generating power in correspondence to various frequencies of sunlight. The overall system is a combination of lenses and mirrors consisting of multi-junction cells.

Considering their success in the past, it is no surprise to learn that Spectrolab is expecting a 40 percent average production efficiency for terrestrial solar cells in 2011.

    @Tom it was 2.30-2.65 a watt back when I was in the market for it. These are more for when weight and space is important in application. I at the time was looking to make a single compact array for solar tracking, less posts, less tracking means you can go higher end with the tracking type and get more out of them making it more like 1.50 a watt. Also powering the conventional home with merely a 9ft² array is nice. Not only that but if optimal placement is limited this remedys that. They’re more space grade so you know you’re getting one really reliable product as well.

    I remember almost buying thousands in cell fragments from them in 04. Very very impressive figures, at the time they had triangles from the cells cornerpieces which were scrap, nearly bought a ton and wired it myself. Glad I didn’t though cause I’m saving to build a house of the likes the world hasn’t seen. Maybe after it’s complete I’d consider that route for further efficiency. I’m looking at blowing all heating and cooling efficiency figures out of the water through design alone as well as record density when it comes to edible vegatation and aquaculture. You’ll probly see it on cleantechnica in about a year or so.

    How much does it cost per watt?
