abstract
This is Part I of the summary of a joint research project on optimum reduction of boronoxygen related degradation and passivated contacts for PERC-based solar cells. It includes the application of investigated technologies into potential future cell designs such as PERT and bifacial solar cells. The joint project was merged from two individual project suggestions and therefore had two parts. Project part I: industrial solution to minimise the negative impact of light induced degradation (LID) investigate and understand the nature of the degradation effect apply the experimental results and concepts to industrially suppress LID develop an optimized integrated firing-regeneration process for industrial application Project part II: tunnel-oxide passivated contacts (TOPCon) for PERC cells and beyond (not part of this abstract, handed in as a separate abstract to this conference). This project summary is intended to inform the international community about the activity and the results in the project. The detailed project report (in German) will be published with the TIB (Technische Informationsbibliothek Hannover, Germany) soon.
