Cu2ZnSnSe4 based solar cells prepared at high temperatures on Si/SiO2 sodium-free substrate.

Abstract

Cu2ZnSnSe4 (CZTSe) solar cells were prepared at high temperatures on Si/SiO2 sodium free substrate. Si/SiO2 was used as substrate to study the formation of CZTSe absorber without the possible influence of Na and for analyzing its compatibility with Si microelectronic technology.

This substrate allowed reaching higher temperatures than the ones commonly used with soda lime glass (SLG). An efficiency of 5.1 % was obtained on Si/SiO2 substrate with our standard process conditions. The first results of the processing at temperatures higher than the usual ones are also reported and discussed.
