Fast Chemical Bath Deposition Process at Room Temperature of ZnS-Based Materials for Buffer Application in High-Efficiency Cu(In,Ga)Se $_{2}$ -Based Solar Cells

Chemical bath deposited (CBD) Zn(S,O) remains one of the most studied Cd-free buffer layers for Cu(In,Ga)Se2 -based (CIGSe) solar cells and has already been implemented at the industrial level for high-efficiency solar cells and modules. Exploring further routes of improvement is demanded and needed. One of the key routes is related to the high reactant concentration and high deposition temperatur...
