摘要：

Sb2S3 was successfully deposited on the TiO2 nanorod arrays with the length of 600 nm, the diameter of 20 nm and the areal density of 520 mu m(-2) by step-by-step spin-coating the SbCl3 solution in methanol and the Na2S solution in methanol/water (v/v, 95/5) via successive ionic layer absorption and reaction. Then the Sb(2)S(3)sensitized TiO2 nanorod arrays were annealed at 300 degrees C for 6 min in an N-2 atmosphere. The corresponding solar cells with Spiro-OMeTAD achieved the photovoltaic conversion efficiency of 3.76%, along with the open-circuit voltage of 0.55 V, the short-circuit photocurrent density of 11.26 mA.cm(-2) and the fill factor of 0.61.
