Copper antimony sulfide (Cu 3 SbS 3 ) is considered a promising photovoltaic absorber material due to its abundance in soil, low cost and environmentally friendly constituents. However, production by methods that require high cost and abundant materials and the differences between the results obtained in the limited number of studies carried out limit the discovery of its photovoltaic performance. In this study, Cu 3 SbS 3 thin films were produced for the first time using spin coating. Optical, morphological and structural characterization of the thin films produced using Cu and Sb in different ratios (0, 0.1, 0.3, 0.5 and 1) was investigated in order to determine the optimum Cu to Sb ratio to form the Cu 3 SbS 3 phase. According to the results obtained, the Cu 3 SbS 3 phase was formed at higher Cu/Sb ratios. In order to produce Cu 3 SbS 3 thin films with improved optical and morphological properties, the film was doped with boron (B), for the first time, and its properties were tested. It was seen that boron doping significantly improved the properties of the Cu 3 SbS 3 thin film. The obtained results showed that the boron doped Cu 3 SbS 3 thin film with improved properties, which can be easily produced using low-cost methods and dopant materials, is a suitable candidate as an absorber layer for high-performance solar cells. For the first time, boron doped Cu 3 SbS 3 thin films were produced via spin coating method. Boron doped Cu 3 SbS 3 thin films will provide new dimensions for the design of environmentally friendly, low cost and highly efficient solar cell absorber layer.
