Characteristics of phosphorus doped silicon layer in tunnel oxide passivated contact solar cell |
초록 |
Today, many group presented high efficiency Si solar cells over 25% in efficiency. One of the promising structures is the TOPCon cell presented by Fraunhofer ISE in Germany. Recently, a 25.1% tunnel oxide passivated contact (TOPCon) cell based on n-type Si was reported. The feature of this cell is the excellent interface passivation quality achieved by applying a thin (< 2 nm) oxide layer. The oxide layer was located between the doped poly-Si and the Si substrate. In this study, we fabricated TOPCon cell by depositing phosphorus doped a-Si and poly-Si each. They act as carrier-selective contacts and, thereby, lead to a significant reduction of the cell's recombination current. We compared these layers by various methods and could get good results from the phosphorus doped Si contact in TOPCon solar cell. |
