PV module manufacturer Astronergy said it was undertaking a transition away from 4BB (busbar) technology to 5BB to boost overall conversion efficiencies at its production plant in Frankfurt (Oder), Germany.
PV manufacturer Astronergy Solarmodule GmbH, a subsidiary of China-based producer, Astronergy and part of Chint Group said it would start production of modules using the latest generation of PERC (Passivated Emitter Rear Contact) cells with monocrystalline wafers to produce high-efficiency ‘all black’ modules in the 295 to 310 Watt peak (Wp) power classes.
