광 포획 향상을 위한 다중 아키텍처 식각 기술을 적용한 박막 실리콘 태양전지에 관한 연구 = A Study on Thin-Film Silicon Solar Cells with Multi-Architecture Etching Technique to Improve Light Trapping

다국어 초록 (Multilingual Abstract)

This work focuses on improving the light-harvesting efficiency of thin-film silicon solar cells through innovative multi-architecture surface modifications. To create a regular optical structure, a lithographic process was performed to form it on a glass substrate through various etching processes, from Etch-1 to Etch-3. AZO was deposited on top of the structures and re-etched to create a multi-architectural surface. These surface-modified structures improved the light absorption and overall performance of the solar cell through changes in optical and physical properties, which we will analyze. In addition, we investigated the effect of post-cleaning on the etched glass structures through EDX analysis to understand the mechanism of the etching action. The results of this study are expected to provide important guidelines for the design and fabrication of solar cells and other photovoltaic devices.
