The year 2016 saw the start of the field of PV becoming highly dynamic in terms of the implementation of innovations within solar cell and module production. Since then, Al-BSF devices have been in decline, as more-advanced and higher-efficiency solar cells and modules begin to enter the PV market, achieving the lowest-cost electricity production. 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. It will be explained why PERC-based IBC processes are the future, not only for rooftop applications but subsequently for the utility-scale market as well. Because of this rapid take-up, FhG ISE, TNO and ISC Konstanz will be reactivating the back-contact workshop in order to bring the whole PV community together again to work on back-contact technology for the PV future.
