In this work nanostructured PbS thin films were deposited on glass substrates at room temperature by radio frequency sputtering technique varying the power from 50 to 150 W while the other parameters were kept constant (Argon flow at 80 sccm for 30 min). It was observed by x-ray diffraction that they have a preferential growth in the (200) direction. Through atomic force microscopy (AFM) it was proved that the films present a nanostructured growth, with particle size between 6 and 8 nm. So it can be said that nanostructured thin films of PbS have been obtained by physical methods at room temperature for future application in solar cells.
