Surface Lifetime Investigation for Characterization and Enhancement of passivating contacts in c-Si solar cells

Project description

Better passivating contacts for higher-efficiency crystalline silicon solar cells

Passivating contacts consisting of a doped polycrystalline silicon layer on top of a thin layer of silicon oxide are promising for bridging the gap between the theoretical and real efficiencies of solar cells based on crystalline silicon. However, their development has so far been based on trial-and-error approaches, thereby limiting understanding of their underlying working principle. Funded by the Marie Skłodowska-Curie Actions programme, the SLICE project will apply lifetime spectroscopy to identify electrically active defects that limit the lifetime of charge carriers at the interface between polycrystalline silicon contacts and crystalline silicon. The characterisation of interfacial defects should facilitate the fabrication of better passivating polycrystalline silicon contacts and ultimately lead to higher-efficiency solar cells.
