Switching to other silicon wafer types (like n-type) was the only practical solution to avoid the negative impact of BO defects on solar cell performance, as pathways for BO defect stabilization were still far from being developed.
The record efficiency rose to 25.6% in 2014 and to 26.7% in 2017 [6, 7] thanks to the heterojunction (HJ) intrinsic thin layer technology based on thin a-Si passivating layers and on interdigitated back contacts (IBCs) on n-type silicon wafers.
Due to the susceptibility of p-type Czochralski (Cz)-grown silicon to BO-LID, such wafers were deemed unsuitable for SHJ solar cells. In addition to stability issues, lower charge carrier lifetimes due to contamination and challenges with surface passivation posed barriers to the adoption of p-type wafers in SHJ applications.
