ZnO/SnS heterostructures were fabricated by electrochemical deposition (ECD) for application to solar cells. SnS was deposited by three-step pulse ECD from a solution containing 100 mM Na2S2O3 and 30 mM SnSO4. To improve the film properties, tartaric acid (C4H6O6) was introduced as a complexing agent into the SnS deposition solution. The deposition with 100 mM tartaric acid resulted in larger optical transmittance and smaller oxygen content. ZnO was deposited on SnS by two steps pulse ECD from a solution containing Zn(NO3)2. Both the heterostructures fabricated with/without tartaric acid showed clear rectifying properties. However, photovoltaic properties were not improved by the addition of tartaric acid.
