Abstract/Summary:

---

Currently, PV industry is looking towards different technologically feasible options of transferring passivating contact or TOPCon cell concept from laboratory research towards industrial manufacturing. In this paper, we perform techno-economic assessment of industrial manufacturing of TOPCon-based solar cells after assessing various process routes based on currently production-ready and upcoming future alternative process technologies. Under given assumptions, TOPCon-concepts are found to remain economically competitive against bifacial PERC in terms of levelized cost of electricity (LCOE), if a minimum absolute gain in cell efficiency > 0.4- 0.6% can be maintained.
