Sunfilm achieves record total-area efficiency for largest thin-film module


Sunfilm has set a world record of 9.6% total-area efficiency for a module of 2.6m x 2.2m. Sunfilm’s Model F achieved a maximum stabilized output power of 546Wp, achieved during a recent process optimization run on the company’s production line. The thin-film deposition rate was the same as the one used for Sunfilm’s normal high-volume production.

Ulrich Wantia, CEO of Sunfilm, said, “With this world record efficiency of 9.6%, Sunfilm is well on track towards its goal of achieving an average module efficiency of 10% over the mid-term. The fact that we are able to demonstrate such efficiency now, is also a key element in our process of strategically realigning the company.  The result clearly also increases Sunfilm’s attractiveness for possible investors.”
