Abstract

The Cu-Sn alloy as a precursor for Cu2SnSe3 (CTSe) thin films was electrochemically co-deposited from a modified electrolyte solution using magnetic steering. The Cu-Sn film on the Mo/glass substrate was continuous, smooth and contained no organic contaminants according to Raman spectroscopy. The current efficiency of Cu-Sn electrodeposition in the solution was about 90%, i.e. significantly higher than that previously reported. The Cu-Sn films with the Cu/Sn ratio in the range of 1.6
