Independent testing agency Société Générale de Surveillance (SGS) Institut Fresenius in Dresden, Germany, has reportedly confirmed that Q.Cells has broken the 300Wp barrier for 60-cell modules with a recorded performance of 301Wp. The module is based on the Q.Antum technology, which Q.Cells notes is under constant development.
The base material for the Q.Antum is made of 180µm thick, n-doped monocrystalline silicon wafers. Q.Cells put functional nano-layers onto the rear side of the wafers and applied metal contacts using a screen-print technique. The company noted that development work was partly supported by the Federal State of Saxony-Anhalt and the German federal government.
