nc-SiC by PECVD for High-Temperature Passivating Contacts

Christophe Ballif, Franz-Josef Haug, Julien Hurni, Ezgi Genç

Institute of Electrical and Electronics Engineers (IEEE)2025

Co-annealing of PECVD boron emitters and poly-Si passivating contacts for leaner TOPCon solar cell fabrication

Christophe Ballif, Franz-Josef Haug, Sofia Libraro, Julien Hurni, Ezgi Genç

This study investigates the feasibility of a single-step annealing process for tunnel oxide passivating contact (TOPCon) solar cell fabrication to replace the conventional two-step approach. We present a novel method using a single thermal treatment to sim ...

Boron-emitter development for TOPCon c-Si solar cells based on plasma-deposited boron diffusion source and poly-Si(n) passivating contact

Christophe Ballif, Franz-Josef Haug, Julien Hurni, Ezgi Genç

The n-type TOPCon technology is currently the leading approach in the industry. Generally, it involves two high-temperature steps that can result in long cycle times and expensive processes. In this context, we propose a lean manufacturing process based on ...
