摘要

Engineering a back electrode is one of the key factors in generating a high performance Copper Indium Gallium Selenide (CIGS) solar cell. For traditional CIGS films grown on soda lime glass (SLG) substrates the back electrode controls Na transport from SLG to CIGS. For CIGS grown on Na-free substrates, such as a stainless steel foil, the back electrode must also be engineered to be a source of Na. MiaSolé flexible solar cells and panels are enabled through the deposition of a back electrode onto a stainless steel foil that contains a Na doped Mo (MoNa) layer. The back electrode Na content and transport properties can be tailored to engineer a CIGS solar cell with good electrical and mechanical properties. This paper shows how the properties of the CIGS are influenced by changing the composition and deposition parameters of this MoNa layer.
