On August 22, 2013, IQE plc, the world's leading supplier of semiconductor wafers, claimed that with the NREL efficiency certification, the efficiency of photovoltaic cells manufactured by the company's high-volume production qualified materials has reached 44.1%. , surpassing the efficiency of the standard three-junction CPV battery from Solar Junction, a former world record creator.

Photovoltaic cells are manufactured by Solar Junction, a Silicon Valley company that develops highly efficient multi-junction solar cells for the concentrated photovoltaic (CPV) market, using high-capacity MBE tools (silicon wafers) produced by IQE.

In October 2012, Solar Junction said that when the sunshine intensity was 947, the Solar Junction battery's power conversion efficiency was 44%, which broke the company's record of 41.35% of the sunshine intensity created in April 2011. Both records are certified by the National Renewable Energy Laboratory.

Multi-junction solar cell production efficiency milestone

Viijit Sabnis, CEO of Solar Junction, said: “Breaking the world record is a major achievement. It is also a testimony of our close cooperation with IQE, Solar Junction diluting nitriding technology, and our outstanding team achievements. We will continue to focus on multi-junction solar cell production. Efficient research and development, and strive to reduce the cost of CPV in order to benefit consumers."

IQE CEO Dr. Drew Nelson said: "Behind our high-capacity 4" and 6" CPV technology is fully certified, battery efficiency surpasses the previous world record data of Solar Junction is another huge achievement of IQE. CPV battery efficiency improvement means The total cost of installation and energy generation can be greatly reduced." (Translator: Krystal)
