New production process could cut solar cell prices by half

• By Ben Coxworth,

Boosting solar cell efficiency is seen as a key factor in making them more practical, but there is another way of looking at the matter ... if the price of those cells were lowered, we could generate more power simply by using more of them. That’s where Mississippi-based Twin Creeks Technologies comes into the picture. The company has developed a method of making crystalline silicon wafers which it says could reduce the cost of solar cell production by half.

Ordinarily, when crystalline silicon wafers are being made for use in solar cells, a chunk of silicon is cut into wafers that are each 200 micrometers thick. According to Twin Creeks, however, only the very surface of that wafer is “active” – the rest is wasted.
