Module press Station for sealing deposition Busbar deposition station Pick & Place stations for ribbons and cells Station for gluing

WHY CHOOSING OUR TECHNOLOGY ?

Objectives 30% direct cost reduction of module manufacturing at least (for similar components). Only 4 operators per shift. (4 times less than the other systems) Cycle time reduction per module from >10 min (EVA) to 2 min (NICE fully automatic 50 MW line) 3 times less footprint New sealing process and material for improved humidity tightness.

Stable long term module performance for more than 30 years.

Fully recyclable modules.

The NICE process is ready for mass module production

  2 lines 25 MW are already built by the company Vincent Industrie (Brignais, France).

Some other lines of 25, 50 MW and 100 MW were ordered.



Certification

 NICE modules have validated IEC 61215 and IEC 61730 normes in June 2010 (TÜV Rheinland) and also in December 2011 

Our R&D team are currently focused on :

   Yield and productivity of the industrial lines.

IEC module certification of the industrial lines and new components.

Using the NICE technology with various cell concepts and types (rear contacts, bifacial cells, thin films…).
