Amorphous silicon enhanced metal-insulator-semiconductor contacts for silicon solar cells

Bullock, James; Cuevas, A.; Yan, D.; Demaurex, B.; Hessler-Wyser, A.; De Wolf, S.


Carrier recombination at the metal-semiconductor contacts has become a significant obstacle to the further advancement of high-efficiency diffused-junction silicon solar cells. This paper provides the proof-of-concept of a procedure to reduce contact recombination by means of enhanced metal-insulator-semiconductor (MIS) structures. Lightly diffused n+ and p+ surfaces are passivated with SiO₂/a-Si:H and Al₂O₃/a-Si:H stacks, respectively, before the MIS contacts are formed by a thermally...[Show more]
