How much feasibility of electrodeposition of SnS layer on electrodeposited ZnO nanostructures to form the ZnO/SnS heterostructure? What is the future scope of this type of heterostructures for photovoltaic applications?
Intrinsic ZnO is a wide band gap material and non conducting in nature. Basically we need a conducting substrate for electrodeposition. How can you fabricate electrochemically such type of heterostructure. The first layer of ZnO is possible and for this you have to optimize the bath parameters properly. For the next layer of SnS you can go for any vacuum technique. Prior to all those experiments, look into a few parameters such as band gap of the absorber layer, band alignment of the heterostructure etc. Thus you can come to a final decision.
Though ZnO is a wide band gap material and non conducting in nature, its conducting ablity can be greatly enhanced under illumination higher than its bang gap.Thus the deposition of ZnO/SnS heterostructure by electrodeposition is feasible.

Dear Zhongqing Liu,
There might be photocorrosion of the material under illumination in aqueous electrolyte. I don't have much idea how one could overcome it.
