Aim of AMPERE is the setting-up of an European sustainable manufacturing full-scale automated industrial pilot line, to produce bifacial heterojunction technology (HJT) silicon solar cells and modules. In this work we illustrate the state of art of AMPERE project, started in May 2017, focusing on its technical results, industrial and economic sustainability and perspectives on LCOE in the frame of vertical integration along with EGP as its natural end-user. These expected outcomes will be assessed and evaluated as a solid backbone to pave the way to the GW factory scaling up. The decision to accelerate in the project timeframe, within 2019, the installation and start-up of a manufacturing line, leading to a nominal capacity of EGP Catania 3SUN site to 200 MWp, will support the demonstration of the viability of HJT solar module massive production in Europe.
