文摘
- •
New analytical model for void formation based on surface energy minimization.
- •
Model is able to describe geometry dependence of voids.
- •
Significantly deeper BSFs for bifacial PERC+ cells (8 µm) compared to PERC (4 µm).
- •
BSF depths can be modeled by the amount of screen printed Al-Paste.
