Within the last 3 years Q CELLS has developed its Q.ANTUM NEO technology based on a passivating contact solar cell and has transferred this technology to mass production. With a very lean and cost-effective process flow a conversion efficiency of 25.2 % has been demonstrated with this solar cell concept while average pilot line efficiency is currently at 24.7 % with a steep learning curve. This enables a high module power output of 444 W (132 half cells M6) corresponding to a module efficiency of 23.9 % on aperture area. The cell structure features a solar cell with passivating contacts on the rear side, double-sided screen-printed metal contacts, a module-optimized anti-reflective coating (ARC) and a homogeneous front-side emitter on a n -type silicon substrate.
