| 제목 | Improving Performance of CIGS Thin Film Solar Cell via Optimization of CdS/CIGS p-n Junction : pH Control of CBD Bath |
| 초록 | For CIGS thin film solar cells, design of p-n junction is crucial because it is closely related to both generation and collection of photo-generated carriers in CIGS layers. CdS/CIGS p-n junction has been most widely employed and achieved the highest solar cell efficiencies. In general, CdS/CIGS p-n junctions are prepared using a chemical bath deposition (CBD) process in which CdS thin film is deposited by immersing CIGS thin film in the bath. As bath conditions in CBD process strongly affect properties of CdS thin film, it is very important to optimize conditions of bath. In this work, pH of immersion bath has been varied to study its effects on the properties of CdS/CIGS junctions as well as performance of CIGS thin film solar cells. It is confirmed that optimized pH condition can remarkably enhance both optical and electrical characteristics of the CdS/CIGS junctions. As a result, cell efficiency of 14.6% is achieved, which is one of the most efficient CIGS thin film solar cells. |
