Synthesis, Characterization, and Performance of Sb2(S, Se)3 based Composites

Thermal evaporation method was used to create the Sb2(S,Se)3 compounds. This finding emphasizes Sb2(S,Se)3's promise as a new photovoltaic material. It has achieved good power conversion rates of 6.5% to 8%. Further efficiency improvement seems to be required for upcoming real-world applications. Sb2Se3-GaSe eutectic composites are synthesized by the vertical Bridgman method. XRD analysis and structural study of Sb2Se3-GaSe eutectics show that Sb2Se3 inclusions are uniformly distributed in the GaSe matrice. Three eutectic points were studied in the Sb2Se3-GaSe system. It was determined that the composition of the three eutectics formed in the Sb2Se3-GaSe systems is 80 wt%; 55wt% and 40wt% Sb2Se3, melt points were 776 K, 725 K and 698 K respectively.
