Fraunhofer Sets New World Record for Multicrystalline Silicon Solar Cell with 21.9 Percent Efficiency

The record Multicrystalline Silicon solar cell consists of n-type high performance multicrystalline silicon, or HP mc-Si. Compared to p-type silicon, this material shows a higher tolerance to impurities, especially iron. Researchers at Fraunhofer ISE have produced a multicrystalline silicon solar cell with 21.9 percent efficiency, which successfully brings the world record back to Freiburg. Higher […]
