Abstract

Antimony sesquisulfide (Sb₂S₃) has emerged as a prospective and attractive material for next-generation solar cells due to its success in solution processing, high stability, low toxicity, and exceptional optoelectronic properties. Exploring the growth properties of Sb₂S₃ films is imperative to further improve the power conversion efficiency (PCE). In this investigation, Sb₂S₃ films were effectively produced through the application of electron beam evaporation, which was subsequently followed by post-annealing treatment. The impact of annealing temperature, duration, and target weight on crystalline orientation, morphology, internal stress, and optical characteristics were examined. The films exhibited a pure orthogonal phase with strong [hk0] crystalline orientation, uniform surface, and large grains after the annealing process. The Raman spectrum analysis demonstrated that sulfur loss in films escalates with increasing annealing temperature and time. The stress in the (hk1) and (hk0) planes increases with the increase of film thickness, and the stress in the former is greater than that of the latter. The synergistic effects of the electron beam evaporation technique and subsequent post-annealing treatment further illustrate the promising potential of Sb₂S₃ for use in solar cells.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
