This paper is to inform about Part I of a joint research project on optimum reduction of boron-oxygen 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. This paper focuses on an industrial solution to minimize the negative impact of light induced degradation (LID) by: • Investigating and understanding the nature of the degradation effect • Applying the experimental results and concepts to industrially suppress LID • Developing an optimized integrated firing-regeneration process for industrial application The second part of this project is also covered in this conference [1]. The detailed project report (in German) has been published [2].
