In the so- called three- element co- electrodeposition method, complexing agent of EDTA was added in order to adjust the electrodeposition potential of Co, Sn and S, so that they could co- electrodeposit and form CoSnS2 thin film of 620nm.

• 在三元共沉积法中,加入EDTA(乙二胺四乙酸二钠)配合剂来调整Sn、Co、S的沉积电势以实现这三种元素的共沉积,从而一步形成厚约620nm的CoSnS2薄膜。
