Russia-based integrated PV manufacturer Hevel Group has claimed its first fabricated heterojunction (HJ) solar cell has achieved a conversion efficiency of 21.75%. 

Hevel noted that the cell efficiency was measured under standard testing conditions in-house and not verified by a third party. 

The company also noted that it was in the final stage of pre-commissioning its solar module manufacturing plant in Novocheboksarsk after deciding to switch from a-Si thin-film production to high-efficiency HJ technology. 

Leading PV manufacturing equipment supplier Meyer Burger landed a US$22.5 million order from Hevel to convert to HJ and bifacial cell production and ‘SmartWire’ module assembly.

The switch, which was announced back in June 2016, would provide a nameplate capacity of 160MW, according to the company.

Hevel’s HJ modules are expected to be used in downstream PV power plant projects in Russia. The company claimed a project pipeline of around 500MW, which includes grid connected and off grid PV plants.
