研究目的
Investigating the potential of replacing Cu conductive backsheets (CBS) with Al and the electrically conductive adhesive (ECA) with cheaper and more robust methods for connecting the foil to the cell in back-contact solar cells to reduce module costs.
研究成果
The study demonstrates the potential of laser welding and thin adhesive layers as low-cost methods for interconnecting Al foil electrodes to cell contacts in back-contact solar cells. The performance and reliability of these methods are highly dependent on the module package, indicating the need for further research to optimize the materials and processes.
研究不足
The study highlights the dependency of the performance and reliability of the interconnection methods on the module package and the ongoing search for a synergistic bill of materials. The susceptibility of epoxy-based interconnects to moisture ingress is also noted as a limitation.
