Figure 6 Efficiency stability measurement of SCH solar cell with and
without back ICO layer
Depositing Ag back electrode directly on the MoOx film
makes the fabrication process simple for the
MoOx/c-Si(n) SCH solar cell with a front-contact
back-junction structure. However, adding a TCO layer between them is
helpful and imperative for improving Jsc, reducing
contact resistance, and improving device stability.
