Na post-deposition treatments are commonly used
to tackle the fine grained layers that are prevalent in solutiongrown CIGS absorber layers. This work studies the effect of an
evaporated NaCl layer on the electrical and morphological
properties of amine-thiol solution-processed CIGS solar cells.
Here, the NaCl layer acts as a post-deposition Na source and its
application resulted in a CIGS device with superior JV
characteristics, including a power conversion efficiency increase
from 1.3% for a Na free glass substrate to 8.4 % with NaCl post
deposition treatment.
