The porous Sb₂S_xSe_3-x thin films with different pore sizes were successfully prepared on the TiO₂ compact layer by the pyrolysis of the precursor solution containing N-butyldithiocarbamic acid, Se, and Sb₂O₃ in DMF and using the relative low spin-coating speed. The effect of the pyrolysis temperature on the chemical composition, optical absorption, crystal phase, and pore size of the porous Sb₂S_xSe_3-x thin films was investigated, and the corresponding solar cells were also fabricated. The results points out that the Sb₂S_xSe_3-x thin film pore sizes decreased with the increase of the pyrolysis temperature from 360 to 440 °C. The porous Sb₂S_xSe_3-x thin films provided a possible path for assembling the hybrid absorption layer with quantum dots.

通过在DMF中热解含N-丁基二硫代氨基甲酸，Se和Sb ₂ O ₃的前驱体溶液，并成功地在TiO ₂致密层上制备了具有不同孔径的多孔Sb ₂ S _x Se _{3- x}薄膜。旋涂速度相对较低。研究了热解温度对多孔Sb ₂ S _x Se _{3- x}薄膜的化学组成，光吸收，晶相和孔径的影响，并制备了相应的太阳能电池。结果指出，Sb ₂ S _x Se_{3- x}薄膜孔径随着热解温度从360到440°C的增加而减小。多孔的Sb ₂ S _x Se _{3- x}薄膜为组装带有量子点的混合吸收层提供了一条可能的途径。
