제목 ZnSnO thin film growth by using atomic layer deposition and applying to buffer layer for CIGS solar cells
초록 ZnSnO thin films were deposited by the Atomic layer deposition(ALD) process using diethyl zinc(DEZ) and Tetrakis-dimethylamino tin(TDMA-Sn) as metal precursors and water vapor as a reactant. In case of CIGS solar cell, CdS is the most popular buffer layer. However, CdS causes environmental problems since the heavy metal, Cd. In order to fabricating Eco-friendly solar cells, ZnSnO can become alternatives. The CIGS solar cells using ZnSnO buffer layer showed 16.48% conversion efficiency. This results can be comparable with conversion efficiency of CdS buffer layer(16.55%).
