Abstract :
Using the electrochemical deposition (ECD) method, we prepared tin sulfide (SnS) thin films, which are suitable for the absorption layer in solar cells because of its bandgap energy (/spl sim/ 1 eV). We investigated the electrical properties of deposited SnS thin films and the properties of contacts with several different metals evaporated on the surfaces. Furthermore, we observed the photoconductivity of the films by means of photoelectrochemical (PEC) measurements. From these results, we confirmed that the SnS thin films show p-type conduction.
