According to a report on the American Compound Semiconductor website on August 20, 2013, the National Renewable Energy Laboratory (NREL) has confirmed that the III-V based solar cell module developed by Amonix in the United States has a conversion efficiency of 35.9%. The testing method is based on the recently passed CPV IEC testing regulations, with a testing condition of 1000W/m2 and a battery temperature of 25 ℃.

Amonix stated that this result is the highest efficiency achieved by any photovoltaic technology and module in history, and it is also the first quantitative rating of photovoltaic modules conducted by a renewable energy laboratory at a working temperature of 25 ℃. Previous quantitative ratings were conducted at the working temperature of the battery.

Amonix and NREL collaborate to promote the maturity of new measurement technologies. In April 2013, under centralized standard working conditions CSOC, the conversion efficiency of the solar cell module developed by Amonix reached 34.9%. In May 2012, the company claimed that this was the first time its solar cell modules had a conversion efficiency exceeding 33% under CSOC conditions.

Vahan Garboushian, Founder and Chief Technology Officer of Amonix, said, "The efficiency of the IEC CSOC module reached 35.9%, which is a direct comparison of the efficiency of photovoltaic modules under IEC standard testing conditions. As solar energy connections continue to produce more efficient batteries, Amonix will produce modules with higher efficiency and break the current world record in the near future
