摘要

The Pb/S/1,2-ethanedithiol composite thin films were successfully deposited on TiO~(2)nanorod arrays by spin-coating step-by-step 5 mmol dm_(−3)Pb(NO~(3))~(2), Na~(2)S and 1% 1,2-ethanedithiol solution and their chemical compositions can be easily adjusted by changing the concentration of Na~(2)S solution from 5 to 3.5 mmol dm_(−3)and 2 mmol dm_(−3). The average crystal sizes of Pb/S/1,2-ethanedithiol quantum-dots decreased from 7.9 to 7.1 nm and 6.5 nm with the decrease of the concentration of Na~(2)S solution and the chemical bonding of Pb_(2+)and S in EDT was chelation of the penta-heterocycle in Pb/S/1,2-ethanedithiol composite thin films. All solid-state Pb/S/1,2-ethanedithiol composite thin film sensitized TiO~(2)nanorod array solar cells using 5, 3.5, 2 mmol dm_(−3)Na~(2)S solution exhibited the photoelectric conversion efficiency of 2.68, 3.41 and 4.51% under the illumination of simulated AM 1.5 sunlight (100 mA cm_(−2)).
