Insights on the thermal stability of the Sb2Se3 quasi-1D photovoltaic technology

This work explores the thermal stability of antimony-based photovoltaic (PV) technologies investigating the effect of low-temperature (50—350¿°C) postdeposition annealings (PDAs) on bare Sb2Se3 absorbers and complete SLG/Mo/Sb2Se3/CdS/i-ZnO/ITO devices (5.7% power conversion efficiency with no anti-...
