Optimization of the Sb₂S₃ Shell Thickness in ZnO Nanowire-Based Extremely Thin Absorber Solar Cells.

ABSTRACT: Extremely thin absorber (ETA) solar cells made of ZnO/TiO₂/Sb₂S₃ core-shell nanowire heterostructures, using P3HT as the hole-transporting material (HTM), are of high interest to surpass solar cell efficiencies of their planar counterpart at lower material cost. However, no dimensional optimization has been addressed in detail, as it raises material and technological critical issues. In this study, the thickness of the Sb₂S₃ shell grown by chemical spray pyrolysis is tuned from a couple of nanometers to several tens of nanometers, while switching from a partially to a fully crystallized shell. The Sb₂S₃ shell is highly pure, and the unwanted Sb₂O₃ phase was not formed. The low end of the thic
