This paper reports on the latest advances in passivated emitter and rear cell (PERC)-based shingled solar cell activities at Fraunhofer ISE. The approach taken is to fabricate 6" host wafers from
Czochralski-grown silicon and separate them after metallization and contact firing into bifacial p-type shingled passivated edge, emitter and rear (pSPEER) solar cells.

The holy grail of every solar cell producer is the creation of a lowcost interdigitated back-contact (IBC) solar cell with an efficiency greater than 25%, a goal that can be found in almost every roadmap presentation. In this paper it will be shown that we are not far away from achieving this target, since IBC devices, with different process complexities, are already in production at several companies.

In this paper, an even greater reduction in wafer thickness, down to 130μm, is evaluated, and the critical steps in terms of breakage rates in cell and module production processes are reviewed. Finally, the mechanical stability and reliability of these thin HJT cells in glass–backsheet and glass–glass module types are addressed.

To embrace the terawatt-scale challenge of the PV market growth, a low-carbon and resource-efficient pathway has to be guaranteed. An approach for doing this is to enable market mechanisms that account for the greenhouse gases emissions, and their associated costs, from PV systems and components.
