Current status of high-efficiency Q.ANTUM technology at Hanwha Q CELLS

In this paper we present the latest results of the high-efficiency Q.ANTUM technology during pilot production at Hanwha Q CELLS. With this dielectric passivated rear cell concept we reach average efficiencies well above 18 % on multicrystalline silicon on continuous running production. The high efficiency cells are converted in an industrial module production with power classes reaching above 270 Wp. We furthermore present field data which show the superior yield performance of modules based on the Q.ANTUM technology during the whole year.
