Antimony sulfide-selenide Sb-2(S,Se)(3) as a promising absorber material has drawn extensive attention owing to its rewarding photoelectric properties, low toxicity, and earth abundant components. Here, an available and highly effective method, in situ hydrothermal growth accompanied with post-selenization, is successfully applied to fabricate Sb-2(S,Se)(3) solar cells. The rationale for the preparation of Sb2S3 precursors by the hydrothermal method is discussed, and detailed characterization of Sb-2(S,Se)(3) films selenized with different temperatures is also carried out. Finally, a solar cell with structure of FTO/CdS/Sb-2(S,Se)(3)/Spiro-OMeTAD/Au is fabricated, which delivers an encouraging 6.14% efficiency with V-oc of 732 mV, J(sc) of 14.6 mA cm(-2), and fill factor of 60.8%. This work provides valuable references for further development and improvement of Sb-2(S,Se)(3) solar cells.
