AI Customer ServiceIn this research, we develop eddy current soldering as a non-contact soldering technique for tabbing the ribbon of PV cells under a layer of glass. The performance of eddy current soldering was studied in detail by changing an induction coil distance to the treated sample from 2 to 4 mm and varying exposure time.
Soldering ribbons mainly play a role in connecting electricity in photovoltaic modules. Therefore, it is of great significance to study the influence of new photovoltaic ribbons on the power of solar cells and photovoltaic modules.
In addition, it will demonstrate an effective in-time analysis and reporting tool, using camera control and failure-mode to load correlation. Ultimately the presented test method and equipment will provide the first available basis for creating a mandatory uniform test standard for soldered ribbon interconnects on silicon solar cells.
The ribbon was first soldered on the negative side where the Ag fingers are. Then the cell was turned around, and the ribbon was soldered on the positive side of the cell. The measured maximum temperatures in Fig. 5 are from the negative side and were extracted from the thermal camera images captured from the top of the ribbon (see Fig. 3 ).
These results indicate that the proposed non-contact soldering approach does not sacrifice solar cell performance but creates a crack-free solder connection at longer exposure times, making it an interesting alternative for further development to be applied to repair and refurbish broken solar panel interconnection through glass.
