Description of the organisation

IFE is an international energy research institute. It is an independent, non-profit, private foundation with about 700 employees. Renewable energy and environmental technology are one of the main research activities at IFE. The Department for Solar Energy (DSE) at IFE has outstanding expertise on preparation and study of Si-based solar cells, materials for solar cells, and electronic defects in semiconductors. The IFE activity within solar cells was initiated about 15 years ago. Today, it has a modern and well-equipped processing and characterization laboratory where, among other activities, a well characterized and stable industrial baseline process is running.IFE has experience on and have developed a set of characterization methods (PL-imaging, lifetime characterization, passivation layer characterization, optical characterization) and simulation tools well suited for analysing and testing new cell concepts.

Role in the Project

IFE will mainly participate in WP 6 “Ultrathin wafer development” and WP7 “Cell processing of ultrathin wafers”. In WP 6 our activity will be related to characterization of thin wafers and in WP7 IFE’s contribution will be related to solar cell design and processing with a main focus on development and implementation of light trapping structures suitable for thin wafers.
