ZnSe Thin Film Buffer Layer for CIGS Solar Cells Deposited from Chemical Solution with Variety Complexing Agents

Chemical solution deposited ZnSe thin films can be proper buffer layer of Cu(In,Ga)Se based solar cells in substitution of CdS for environmental consideration, and complexing agents played vital role in chemical solution deposited ZnSe. Ammonia, hydrazine hydrate and triethanolamine have been applied as the complexing agents in chemical solution precursor to get the ZnSe films. Microstructure of the obtained ZnSe films were characterized and the growth property of films with variety complexing agents have been investigated to explorer the state of art in Cu(In,Ga)Se based thin film solar cell fabrication.
