Abstract
The porous Sb2SxSe3-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 Sb2SxSe3-x thin films was investigated, and the corresponding solar cells were also fabricated. The results points out that the Sb2SxSe3-x thin film pore sizes decreased with the increase of the pyrolysis temperature from 360 to 440 °C. The porous Sb2SxSe3-x thin films provided a possible path for assembling the hybrid absorption layer with quantum dots.
