In this work, the effect of adding sodium chloride (NaCl) in zinc oxide (ZnO) electron transport layer (ETL) on the photovoltaic performance of lead sulfide (PbS) quantum dot (QD) solar cells is investigated. To elucidate that, PbS QD solar cells with pristine ZnO and NaCl passivated ZnO...
The low modulus value at 10−2 Hz obtained at the beginning of the exposure shows that the film does not prevent the electrolyte from reaching the substrate or the surface of the zinc particles and does not hinder the electron transfer. This is related to the structure of the zinc-rich ...
