Development of thin high-efficiency large-area interdigitated back contact silicon heterojunction solar cells for mass production (HET-IBC)

Résumé des résultats (Abstract) (Anglais)

The HET-IBC project aims at the development of an industrial process for the manufacture of highefficiency large-area interdigitated back contact silicon heterojunction solar cells on thin Si wafers. This type of device is amongst the most promising ones for ultra-high conversion efficiencies, low production costs and easier assembly into solar modules. Large-area solar cells will be realized at the end of the project, aiming at > 21% efficiency. The target of the industry is to deliver the equipments for wafer sawing and for cell manufacturing with the related processes.
