In the photovoltaic (PV) industry, encapsulation technology is one of the key factors affecting the performance and lifespan of PV modules. In recent years, liquid silicone rubber (LSR), as a new type of encapsulant, has gradually become an "innovator" in PV encapsulation technology, bringing new possibilities for improving PV module performance and reducing costs.

Replacing Traditional Films, Enhancing Encapsulation Quality

Traditional PV module encapsulation mainly uses materials such as EVA films. However, these materials are prone to yellowing, reduced light transmittance, and delamination during long-term use, leading to a decline in module power generation efficiency. LSR, on the other hand, offers excellent heat aging resistance, UV radiation resistance, and corrosion resistance, effectively solving these problems. By using LSR for encapsulation, both the power generation efficiency and service life of PV modules are significantly improved.

Precise Lamination Process, Increasing Production Yield

The LSR encapsulation process uses a lamination method that offers higher precision and flexibility compared to traditional lamination processes. This method involves uniformly applying the liquid rubber to the glass surface, then laminating it onto the solar cells, followed by curing. This process allows for precise positioning, avoiding issues such as micro-cracks in the cells, thereby increasing production yield. Furthermore, the lamination process allows for rework, reducing production costs and risks.

Cost Reduction, Significant Economic Benefits

From a cost perspective, LSR encapsulation technology also offers significant advantages. Due to the different curing pathways between film-type encapsulants and liquid rubber, the weight of adhesive used per unit area is reduced. This means that for module manufacturers, the procurement value per GW of encapsulant is expected to decrease by approximately 30%. For large-scale PV power plants, this represents considerable cost savings. Therefore, LSR encapsulation technology offers high economic viability and is expected to see wider adoption in the future.

Driving Technological Progress, Leading Industry Transformation

The emergence of LSR encapsulation technology not only improves PV module performance and reduces costs but also drives technological progress across the entire PV industry. As LSR technology continues to mature and refine, it is expected to become the mainstream choice for next-generation PV encapsulation. This will lead the PV industry toward a more efficient, environmentally friendly, and economical direction, making even greater contributions to global energy transformation and sustainable development.
