Product Overview
High-Temperature Solar Cell Positioning Tape is specially designed for photovoltaic module manufacturing and EVA lamination processes. Featuring an ultra-thin transparent PET backing coated with high-performance silicone adhesive, the tape provides reliable temporary fixation of solar cells while maintaining excellent optical appearance after lamination.
Its low-outgassing formulation helps reduce bubble formation during the lamination process, ensuring precise cell positioning and improved module quality. With excellent resistance to heat, UV exposure, and aging, this tape is widely used in double-glass solar modules and other demanding photovoltaic assembly applications.
Manufactured under strict quality control standards, the tape is available in roll, slit-roll, and custom die-cut formats to meet different production requirements.

Why It Matters
Common Problems During Module Assembly
❌ Solar cells may shift during handling and lamination.
❌ High lamination temperatures can cause adhesive failure.
❌ Excessive gas release may lead to bubble formation inside the module.
❌ Visible adhesive residue can affect the appearance of finished panels.
How Our Tape Helps
✔ Maintains accurate solar cell positioning throughout assembly.
✔ Withstands EVA lamination temperatures up to 180°C.
✔ Low-outgassing adhesive minimizes bubble formation.
✔ Transparent construction leaves no visible trace after lamination.
✔ Provides reliable long-term stability for photovoltaic modules.
Typical Applications
• Solar Cell Positioning
Used to temporarily secure solar cells before EVA lamination, helping maintain accurate alignment throughout the manufacturing process.
• Double Glass Solar Modules
Provides stable fixation between photovoltaic components while preserving the clean appearance required for double-glass panel designs.
• EVA Lamination Process
Designed to withstand elevated lamination temperatures without adhesive degradation or residue issues.
• Wiring Harness Alignment
Helps organize and secure internal wiring during photovoltaic module assembly.
