Technical Principle
Core Concept
Half-cut technology divides standard solar cells into two halves using precise laser cutting, then reconnects them with a partitioned parallel circuit design, significantly reducing internal resistance losses.
Key Formula: Power Loss = I2 × R
Current halved → Resistance loss reduced to one-fourth of original

Core Advantages
Higher Power Output
Internal resistance loss reduced by over 70%, significantly boosting power generation
Better Shade Tolerance
Partitioned design halves the impact of partial shading, improving performance in low-light conditions
Lower Operating Temperature
Reduced resistance loss lowers operating temperature by 2~3°C, minimizing temperature-related losses
Extended Lifespan
Reduced hot spot risk and slower material degradation extend module lifespan
Key Technical Highlights
Precision Laser Cutting
Utilizes high-precision laser cutting to ensure smooth, damage-free edges that preserve cell efficiency. Minimal heat-affected zone prevents micro-cracks.
Intelligent Partition Design
Modules are divided into independent upper and lower generation zones. Shaded areas affect only half the module, with the other half operating normally.
Low-Current Operation
Halved current reduces power loss to one-fourth (P_loss ∝ I2), lowering hot spot risks while reducing temperature-related power degradation.
Practical Application Value
Snow Cover/Leaf Shading
When the lower half is covered by snow, the upper half continues generating power, significantly reducing production loss compared to traditional modules.
High-Temperature Regions
Every 1°C reduction in operating temperature increases energy yield by 0.5%. Half-cut technology's thermal advantages are especially valuable in hot climates.
Dust-Prone Areas
Localized soiling affects only part of the module, maintaining higher overall performance and reducing cleaning frequency.
Industry Compatibility
Half-cut technology seamlessly integrates with all mainstream PV technologies, providing synergistic benefits
Combined with bifacial technology, total efficiency reaches:
