High efficiency Cu(In,Ga)Se2/CdS thin film solar cells obtained with precursors sputtered from InSe, GaSe and Cu targets

► Development of sputtering and rapid thermal H2Se-free process to grow Cu(In,Ga)Se2 ► Use of sputtering to deposit a buffer layer, in this case CdS ► Preparation of Cu(In,Ga)Se2 solar cells using vacuum process only
