Abstract :
This paper presents a thermodynamic study of Chemical Bath Deposition (CBD) of zinc sulfide based films in aqueous solution. The aim is a better understanding of the effect of temperature and pH on the deposition mechanism and film composition. The formation of solid phases has been predicted by means of the precipitation conditions of ZnO, Zn(OH)2 and ZnS as a function of temperature between 298 and 363 K. Films have been deposited, without ammonia, on the basis of calculated diagrams and first results on solar cells based on electrodeposited CuIn(S,Se)2 layers have been demonstrated
