We deposited CuInSe2 or CuIn1-xGaxSe2 on the substrate of bi-layer Mo by electrodeposition. Besides, we deposited bi-layer Mo by RF sputtering on soda-lime glass. First, we discussed the characteristic of Mo metal, and how can we have a good adhesion and a low resistivity simultaneously. Then, we deposited CuInSe2 and CuIn1-xGaxSe2 thin film by electrodeposition, and discussed the effect of depositing time, pH value in depositing solution, depositing current and different concentration ions respectively.
