[4] In July 2012, Amonix set the world record for photovoltaic module efficiency at 33.5% (full regression analysis) under nominal operating conditions, verified by the National Renewable Energy Laboratory.

[5][6] In April 2013, Amonix broke the record set in July 2012, demonstrating photovoltaic module efficiency at 34.9% (full regression analysis) under normal concentrator standard operating conditions, also verified by the National Renewable Energy Laboratory.

[7] In August 2013, Amonix announced it had achieved a 35.9% photovoltaic module efficiency rating under concentrator standard test conditions (CSTC) as calculated by NREL.

Amonix was founded in 1989 by CPV solar technology developer, Vahan Garboushian,[9] its current chief executive officer and chairman of the board of directors.

Sewang Yoon who developed high efficiency silicon back junction solar cell for HCPV application was co-founder of Amonix.

[17] Amonix previously raised $25 million in Series A funding,[18] and also received $15.6 million in cost-share grant funding through the DOE's Solar America Initiative to improve the reliability and reduce the cost of solar electricity to meet national goals (measured as the levelized cost of electricity) of 6 cents per kilowatt hour by 2015.

[25] Used in conjunction with concentrator optics such as Fresnel lenses, multijunction solar cells are capable of converting sunlight into electricity exceeding 40 percent efficiency.

[28] In April 2013, Amonix broke its own world record for photovoltaic module efficiency at 34.9% (full regression analysis) under nominal operating conditions, verified by the National Renewable Energy Laboratory (NREL).

[29] In August 2013, Amonix announced that it had achieved a rating of 35.9% (full regression analysis) under standard concentrator test conditions (CSTC), calculated by NREL.

In the press release Amonix comments that the CSTC result is a direct comparison to PV module efficiencies which are often reported under standard test conditions.
