Q.ANTUM – Q-Cells Next Generation High-Power Silicon Cell & Module Concept

In this paper we report on our latest R&D cell and module results based on double-side contacted ptype Si solar cells characterised by a dielectric passivated rear surface and local point contacts – our so-called Q.ANTUM technology. In addition to our confirmed 19.5 % efficient world record multi-crystalline Si solar cell we present a new Q.ANTUM module with a world record energy conversion efficiency (ap) of 18.1 % based on 60 multi-crystalline cells. For p-type mono-crystalline Cz material we report on an independently confirmed cell efficiency of 20.2%. Furthermore, supported by R&D results Q-Cells decided to transfer the Q.ANTUM technology into pilot production in Thalheim, Germany. Finally, measurement results are reported demonstrating the maturity of our Q.ANTUM technology concerning reliability and secured energy yield.
