This study report fabrication and characterization of Tin Sulphide based thin film solar cell. The solar cell was fabricated using simple two electrodes electro-deposition technique to deposit window (ZnS) and absorber layers (SnS) on an ITO coated glass slide and Silver paste was pasted on absorber layer as back contact of the cell. The device was characterised using solar simulator at 1.5 AM with Keithley source metre coupled with interactive characterisation software to obtain both dark and illuminated I-V characteristic of the cell. From characteristic curves of the cell, the Voc is read to be 0.17 V; Isc to be -2.85x 10-8A; Vmax to be 0.06 V and Imax to be -1.21x10-8A. Thus, the fill factor (ff) was calculated to be 0.15 while the efficiency below 1 % was computed for the cell. The study therefore concludes that a SnS based thin film solar cell free of Cd is feasible and recommend further research to improve the efficiency of the cell.
