Diego Tonini received the M.S. degree in Material Science from the University of Padova, Italy in 2003 and a post-graduation master degree in surface treatment from University of Padova and National Institute of Nuclear Physics (INFN) in 2004. From 2004 to 2006 worked as research fellow at Legnaro National Laboratories of National Institute of Nuclear Physics (LNL – INFN) in Legnaro, Italy; and from 2006 to 2008 was Reasearch Fellow at Milan Polytechnic in Milan, Italy. He Joined Applied Material in 2009, working as a process Engineer at Baccini Cells System R&D Laboratory in Treviso, Italy. In October 2017 became Product manager for the Applied Materials’ shingling technology solutions. His main research interests are the application to laser processes to c-Si solar cells and the development and industrialization of new cells concepts (selective emitter, MWT. PERC.) He is co-author of more than 20 publications in the field of material science, coatings and C-Si solar cells, with an H-index of 6 as well as several patents concerning solar cells metallization processes.

Shingling technology is an extremely interesting development of cell interconnection in a module is due to higher power densities at same or lower cost, better energy yield, and good reliability. Shingled modules provide lower ohmic losses, better area utilization, lower processing temperature, lower operating temperature resulting in enhanced energy yield, improved aesthetics. In this work we demonstrate the performance gain obtained with shingling interconnection technology in terms of module output power and reliability.
