Biography

Sébastien Dubois studied materials sciences at the National Institute for Applied Sciences (INSA) in Lyon, and graduated with an engineering degree in 2004. In 2007 he received his Ph.D. in Physics from Marseille University. After joining CEA-INES in 2007, he conducted and supervised researches in the field of defect engineering for crystalline silicon solar cells. He is currently responsible for the homojunction silicon solar cells laboratory, with activities on mainstream cell technologies, passivated contacts and new PV concepts.

Topic

New advances in high efficiency solar cells: from heterojunction and high-temperature passivated contacts to tandem

Abstract

For more than 15 years, CEA-INES has been strongly committed in research activities for the development and industrialization of high efficiency solar cells.

In this presentation, the latest results obtained at CEA-INES on silicon heterojunction and polysilicon-based passivated contact devices will be presented.

Innovative approaches and processes will be proposed to speed up the mass-production adoption of these technologies.

Then insights will be given into the implementation of these advanced structures (heterojunction, poly-Si contacts) into perovskite on silicon tandem cells.
