Abstract

This article provides an examination of the long-term potential of antimony selenide (Sb2Se3) as a leading photovoltaic absorber by considering lessons learned from the developmental route of CdTe. We consider the inherent advantages of Sb2Se3, such as its ability to function efficiently in both substrate and superstrate configurations, its grain boundary tolerance, and wide scope of deposition possibilities. By drawing parallels with the historical evolution of CdTe solar cells, we highlight critical lessons that could guide the optimization of Sb2Se3 devices, including the importance of understanding and controlling doping mechanisms, band-gap grading, and device structure on performance. We also consider the feasibility of adapting existing CdTe production capabilities for Sb2Se3 fabrication, which could potentially lead to reduced production costs and shorter energy payback times. Despite the challenges and uncertainties that lie ahead, we argue that the promise shown by Sb2Se3 warrants significant research and development efforts, with the view of making it a viable contender in the solar industry.
