1Productivity
If conventional separate processes are used for mechanical bonding and electrical interconnection of solar elements, then each process can be optimized independently, but the overall production efficiency decreases and multiple process steps are required
Solution Approach 1:
The patent combines mechanical bonding and electrical interconnection into a single integrated process step by applying conductive adhesive directly to the solar elements during assembly. This eliminates the need for separate bonding and electrical connection processes, thereby increasing production efficiency while reducing the number of process steps required.
Solution Approach 2:
The conductive adhesive serves dual functions simultaneously: it provides mechanical bonding between solar elements and establishes electrical interconnection between them. This multi-functionality allows a single material application to achieve both structural and electrical requirements, streamlining the manufacturing process.
2Productivity
If individual handling of solar elements is performed for adhesive application, then precise adhesive placement can be achieved, but the assembly process becomes time-consuming and less efficient
Solution Approach 1:
The conductive adhesive is applied to the solar elements in advance during the transfer process, before the final assembly position is reached. This preliminary application allows the adhesive to be in place when the elements are positioned, enabling continuous assembly without stopping for adhesive application and maintaining both speed and precision.
Solution Approach 2:
The transfer carrier serves as an intermediary mechanism that transports the solar elements while the adhesive is being applied. This intermediary system allows for controlled adhesive application during transfer, ensuring precise placement without requiring individual handling at the final assembly position, thus maintaining both precision and efficiency.
