NORD STORM

“NORD STORM” is to develop next generation industrial silicon heterojunction (SHJ) solar cell and modules which exceed the current amorphous Si based SHJ technologies through several breakthrough technologies: industrially compatible thin film deposition of transition metal oxide to optimize passivation, carrier-selectivity and transparency; new transparent conductive coating to avoid Indium consumption; reliable Cu based metallization and polymer based electrically conductive adhesive used interconnection to reduce the Ag consumption for cost saving. As a goal, the conversion efficiency of the next generation SHJ cell will reach over 25%.
The new technology development in this project will push the solar cell conversion efficiency to a new level beyond the current passivated emitter and rear cells (PERC). Additionally, we will demonstrate this new technology in perovskite/silicon tandem architecture with efficiencies above 30%. In the meantime, the consumption of the Ag and indium will be benefit to both cost reduction and sustainability. The consortium comes from 3 different countries with leading research institutions and active industry partners in Europe within PV research community, will develop the technologies from TRL of around 3-4 to 6 in this project, thus to strength the Europe leadership within PV. Due to the applied breakthrough technologies, the project is quite relevant to Module 2.2 (TRI 2): Through breakthrough R&D to increase the energy efficiency.
