Multi-Layer Interconnection Tape for Solar Cell Modules

The patent applies the composite materials principle by combining multiple tape layers with different functions: a first tape layer carries the tabbing wires while a second tape layer provides additional mechanical support and thermal stability. This composite structure enhances contact reliability under thermal cycling without significantly complicating the manufacturing process, as both layers can be applied in sequence during module assembly.

The patent implements the dimensionality change principle by transitioning from a single-layer tape structure to a multi-layer tape configuration. The addition of a second tape layer creates a three-dimensional layered structure that provides both mechanical reinforcement and improved thermal management, thereby enhancing contact reliability while maintaining manufacturing feasibility through sequential layer application.

The patent applies the intermediary principle by introducing a second tape layer as a mediator between closely spaced tabbing wires. This intermediate layer provides physical separation and support, preventing direct contact and potential short circuits between adjacent wires while allowing the wires to remain close together to minimize shading. The second tape layer acts as a buffer that maintains wire integrity and spacing.

The patent implements the beforehand cushioning principle by pre-positioning the second tape layer to provide protective cushioning between closely spaced tabbing wires before thermal cycling or soldering processes occur. This preventive measure ensures that wires maintain proper spacing and mechanical support throughout subsequent manufacturing and operational phases, preventing connection faults that would otherwise occur with closely spaced wires.
