Chlorine activated stacking fault removal mechanism in thin film CdTe solar cells: the missing piece
Publikováno v:
Nature Communications, Vol 12, Iss 1, Pp 1-9 (2021)
Stacking fault removal and improvement in CdTe solar efficiency is known to be correlated, yet the nature of the relationship is not well-established. Here, the authors explain the passivation process responsible for this improvement, and also elucid
