As photovoltaic (PV) technology has progressed, many types of modules have emerged, such as N-type modules, which provide enhanced performance and efficiency. A key consideration in maximizing the performance of N-type modules is the choice of adhesive materials. In the context of solar applications, this paper examines the unique qualities that pure POE (Polyolefin Elastomer) sticky film offers. It explores the rationale for the choice of pure POE adhesive sheets for N-type modules in particular. Industry professionals may improve the performance and dependability of N-type PV modules by making educated judgments based on their knowledge of the features and advantages of pure POE adhesive films.

Synopsis of Solar Cell Adhesive Films

PV module assembly and encapsulation depend heavily on photovoltaic adhesive films. They offer environmental protection, electrical insulation, and structural stability. Polyolefin (PO), polyvinyl butyral (PVB), and ethylene-vinyl acetate (EVA) are common polymers used to make adhesive films. Every material has unique qualities that determine which module types and applications are best suited for it.

Distinguishing Between Pure POE Adhesive Film

For N-type PV modules, pure POE adhesive film is a unique option for a number of important reasons:
a. Optimal Encapsulation of N-Type Modules: To ensure dependable and efficient operation, N-type PV modules frequently need high-performance encapsulation materials. The N-type backsheet and front glass adhere to pure POE adhesive film with remarkable strength, creating a strong encapsulation barrier that shields the module from moisture, UV light, and mechanical stress.
b. Enhanced Resistance to Potential-Induced deterioration (PID): PV modules are susceptible to the PID phenomenon, which eventually results in power deterioration. PID is particularly prone to affect N-type modules. When compared to other adhesive materials, pure POE adhesive film exhibits a higher resistance to PID, which aids in preserving the long-term dependability and performance of N-type modules.
c. Improved Thermal Stability: Because N-type modules have better heat dissipation characteristics, they frequently function at greater temperatures. Excellent thermal resilience is exhibited by pure POE adhesive film, guaranteeing dependable performance even at high temperatures. It keeps the module’s structural integrity intact and lowers the possibility of adhesive delamination.

d. Reduced Light-Induced Degradation (LID): PV module performance is also impacted by this degradation mechanism. It has been demonstrated that pure POE adhesive film reduces LID in N-type modules, enhancing the modules’ initial power output and long-term stability.

The features and benefits of pure POE adhesive film

The following qualities of pure POE adhesive tape make it appropriate for use with N-type modules:
a. High Transparency: Maximum light penetration to the solar cells is made possible by the high light transmittance of pure POE adhesive film. Since N-type modules frequently use cutting-edge cell technologies like back-contact or passivated emitter rear contact (PERC) cells, this feature is very crucial.

b. Outstanding Resistance to Moisture: Moisture intrusion can cause PV modules to function worse and possibly fail. Superior moisture resistance is provided by pure POE adhesive film, which keeps water vapor out and preserves the long-term dependability of the module.

c. Good Thermal Conductivity: When compared to conventional P-type modules, N-type modules have superior heat dissipation characteristics. Pure POE adhesive film has a high heat conductivity, which makes heat transfer more effective and enhances the dependability and performance of modules.
d. Compatibility with N-Type Backsheets: Specific backsheets with varying material compositions are often used with N-type modules. Pure POE adhesive film ensures strong adherence and long-term durability with its good compatibility with different N-type backsheets.

Study and Industry Acceptance

In the solar sector, pure POE adhesive film’s appropriateness for N-type modules has been thoroughly investigated and acknowledged. Research results and real-world applications show how pure POE adhesive film can improve the performance, lifespan, and dependability of N-type photovoltaic modules.

N-type photovoltaic modules are encapsulated differently thanks to pure POE adhesive film. It is the material of choice for maximizing the performance and dependability of N-type modules because of its attributes, which include outstanding adhesion, resistance to PID and LID, thermal stability, and compatibility with N-type backsheets. The unique needs of N-type module technologies are met by the pure POE adhesive film’s superior transparency, moisture resistance, and thermal conductivity. Manufacturers and researchers can contribute to the advancement and adoption of this potential photovoltaic technology by improving the overall efficiency and long-term durability of N-type solar modules by using pure POE adhesive film.
