Nowadays there are two main approaches to produce CIGS solar cells: sputtering followed by selenization evaporation and coevaporation process. High efficiency solar cells are obtained by the sequential threestage co-evaporation process. On the other hand sputtering system is more suitable for an industrial application but the efficiencies are systematically lower. In our laboratory we have developed a new hybrid sputtering and evaporation system to obtain a scalable process combining the advantages of both techniques. This technique has been already applied to deposition on glass and stainless steel substrates. Quite good results were obtained reaching an efficiency of 15% on glass and 13% on stainless steel substrates respectively. In this paper we report the results obtained on polyimide and thin boron silicate glass (100um) films.

Abstract
Nowadays there are two main approaches to produce CIGS solar cells: sputtering followed by selenization evaporation and coevaporation process. High efficiency solar cells are obtained by the sequential threestage co-evaporation process. On the other hand sputtering system is more suitable for an industrial application but the efficiencies are systematically lower. In our laboratory we have developed a new hybrid sputtering and evaporation system to obtain a scalable process combining the advantages of both techniques. This technique has been already applied to deposition on glass and stainless steel substrates. Quite good results were obtained reaching an efficiency of 15% on glass and 13% on stainless steel substrates respectively. In this paper we report the results obtained on polyimide and thin boron silicate glass (100um) films.
