硫化锑-硒化物Sb-2（S，Se）（3）由于具有良好的光电性能、低毒性、富含稀土元素等优点，作为一种很有前途的吸收材料受到了广泛的关注。本论文采用一种有效的方法--原位水热生长结合后硒化，成功地制备了Sb-2（S，Se）（3）太阳电池。讨论了水热法制备Sb_2S_3前驱体的基本原理，并对不同温度硒化的Sb_2（S，Se）_3薄膜进行了详细的表征。最后，制备了FTO/CdS/Sb-2（S，Se）（3）/Spiro-OMeO 2/Au结构的太阳电池，获得了令人鼓舞的6.14%的效率，V_（oc）为732 mV，J（sc）为14.6 mA cm（-2），填充因子为60.8%。本工作为进一步开发和改进Sb-2（S，Se）（3）太阳电池提供了有价值的参考。
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.
