はじめに

Solar power has received a lot of attention recently due to the rising need for clean and renewable energy sources. PV (photovoltaic) systems are essential for transforming solar power into electricity. The encapsulation film, which shields solar cells from harmful environmental elements including moisture, dust, and mechanical stress, is one of the main parts of PV systems. Due to its superior mechanical and thermal qualities, polyolefin elastomer (POE) is a material that is frequently utilized as an encapsulating layer.

Photovoltaic Encapsulation Film Based on POE

By copolymerizing ethylene and olefin monomers like propylene, butene, and hexene, polyolefin elastomer (POE) is created. Excellent elasticity, flexibility, and toughness characterize the produced material. The PV industry has made extensive use of POE-based encapsulation films because of their better mechanical stability, moisture resistance, and UV resistance. There are many kinds of POE-based encapsulation films, including mono-layer, co-extruded, and multi-layer structures. The exact application and performance specifications will determine which encapsulation film is best.

A case study

In-depth research has been done on the use of POE-based photovoltaic encapsulation film in the literature. In one of the case studies, a 30-kW rooftop PV system in Singapore had its POE-based encapsulating films evaluated. The purpose of the study was to evaluate the encapsulating film’s durability under external weathering conditions. According to the findings, even after three years of exposure to outside elements, the POE-based encapsulating film retained its mechanical strength and transparency.

Another German case study looked at the application of POE-based encapsulation films in hybrid PV modules. By sandwiching a small layer of glass between a POE-based encapsulation film and a PV module, the study hoped to increase the mechanical stability and thermal performance of the PV modules. The findings demonstrated superior thermal management and mechanical stability under thermal and mechanical stress in the hybrid PV modules. Additionally, compared to standard PV modules, the hybrid PV modules had a greater power output.

Success Examples

The PV industry has had a number of successes as a consequence of the deployment of POE-based encapsulating films. The use of POE-based encapsulation films in a 1 MW rooftop PV system in Japan is one success story. The encapsulating film had difficulties since the system was deployed in a hot, humid area. Although the POE-based encapsulating film maintained its mechanical strength and transparency throughout the process, it also showed outstanding resistance to moisture and heat. The success story demonstrated that POE-based encapsulation films can endure adverse environmental conditions and enhance the PV systems’ long-term performance.

The use of POE-based encapsulation films in floating PV systems is another example of success. Because of its adaptability and capacity to make the best use of open water bodies, floating PV systems are becoming more and more popular. The efficiency and robustness of floating PV systems have increased because to the introduction of POE-based encapsulation films. For floating PV systems to function, the encapsulation layer must offer exceptional protection against moisture, UV rays, and mechanical stress.

結論

In conclusion, there are many case studies and success stories in the PV sector as a result of the use of POE-based photovoltaic encapsulation film. The mechanical and thermal performance of POE-based encapsulation films has been good, and they offer the best defense against the outside environment. The case studies and success stories have emphasized the advantages of utilizing POE-based encapsulation films in PV systems for long-term performance and efficiency. The usage of POE-based encapsulation films is anticipated to rise as the demand for renewable energy rises in order to ensure the reliable and sustainable functioning of PV systems.
