CdS 박막의 증착 후처리 방법이 CIGS 태양전지 특성에 미치는 영향

다국어 초록 (Multilingual Abstract)

Chemical bath deposited CdS thin films are receiving increasing attention due to their promising role as a superior buffer layer for conventional Cu(In,Ga)Se2 (CIGS) solar cells. However, CdS thin films contain colloidal particles due to the residual surface layer from precipitation, which strongly influence the performance of solar cells. Hence, it is important to remove residual solution in order to achieve a high quality CdS thin films. We applied three post-deposition treatments to CBD CdS thin films. (ⅰ) Immediate drying of CdS film with N2 gas (ⅱ) Immersion of CdS film into D.I water at room temperature (ⅲ) Immersion of CdS film into D.I water at high temperature. The effects of each treatment on the performance of CIGS solar cell was then determined. The sample treated with the high temperature D.I water showed the greatest efficiency, including the highest JSC and fill factor (FF).
