Only PERC
Module technology: EGing has made the transition to using only passivated emitter rear contact (PERC) technology, leaving behind older cell concepts. The company has developed a frameless glass-glass p-type bifacial module called Janus-II, to be launched in January 2018.
At the beginning of November 2017, Chinese manufacturer JinkoSolar achieved a world record 23.45% cell efficiency for monocrystalline silicon-based passivated emitter rear contact (PERC) technology. Jinko’s competitor in the mono space, Longi Solar, is not far behind, having achieved 22.71% cell efficiency just a few weeks earlier. Thanks to advances in production tools for PERC …
