摘要：

In this paper, we prepared the nanocrystalline US films on the indium-doped tin oxide (ITO) glass substrates using a doctor-blade technique. The source US powder was first prepared by a hydrothermal method and then ground into a screen-printing paste by adding ethyl cellulose as a binder and terpineol as a solvent. The CdS samples were characterized by XRD, SEM, TEM, and UV-Vis diffuse reflectance spectroscopy. A photocurrent of 3.51 mA/cm, a fill factor of 0.44, an open circuit photovoltage of 0.50 V, and a conversion efficiency of 2.2% were obtained under a simulated solar illumination of 35 mW/cm(2), when the CdS film was annealed at 380 degrees C in air for 30 min. The maximum quantum efficiency of 5.5% was obtained at an incident wavelength of 500 nm. Our method provides a general way to prepare electrodes of metal chalcogenide nanocrystalline films.
