Aplicación de agentes de acoplamiento de silano en películas solares fotovoltaicas

1. An overview of agents that couple silanes

An organic substance that is a unique reagent that is frequently utilized in the chemical industry is silane coupling agent. To enhance a material’s qualities, it can blend organic materials like rubber, plastic, and resin with inorganic materials like glass, metal, and ceramics.

2. The function of solar photovoltaic films’ silane coupling agents

Within the photovoltaic supply chain, photovoltaic modules are made up of a specific quantity of solar cells packaged and wired in series and parallel. They are the main part of the solar power generation system and perform the job of photoelectric conversion in the photovoltaic power plant.

The seven main components of a photovoltaic module are glass, cells, packing film, aluminum alloy frame, backsheet, junction box, and adhesive for the module. Photovoltaic module packaging is the primary usage for encapsulation film. It is a crucial component in solar power systems. It contributes to the packing and safeguarding of solar cell modules. As seen in the image below, it can increase the module’s photoelectric conversion efficiency and lengthen its service life. Consequently, a crucial element in determining the lifespan and quality of solar module goods is the encapsulating layer.
Solar photovoltaic films rely heavily on silane coupling agents. Silane coupling agents have the potential to enhance the stability and longevity of solar photovoltaic films by augmenting their adhesion and endurance. Second, silane coupling agents can improve solar photovoltaic films’ resistance to water and humidity as well as their UV resistance.

 

3. How silane coupling agents affect solar photovoltaic film performance

Currently, EVA and POE are the two main materials used to make photovoltaic cell encapsulation films. These polymers are created by hot pressing and cross-linking to enclose and safeguard the cells. They are extensively utilized in battery components due to their better adhesion, endurance, optical qualities, and other attributes.
In order to meet the requirements of long-term outdoor working when solar modules are employed in power plants, EVA/POE packaging sheets must always maintain light transmission, high adhesion, and long service life. EVA resin, also known as POE resin, is the primary raw material used to make photovoltaic packaging film. Proper cross-linking, coupling, and other additives are then added, and the mixture is melted and extruded before being calendering or cast. When this packing film is left out at room temperature, it is not viscous. The bonding performance between glass and EVA encapsulation film can be enhanced by the application of silane coupling agents. Its molecular structure possesses the qualities of both organic and inorganic substances, which accounts for its good resistance to heat, moisture, weathering, and surface tension.

The performance and quality of EVA/POE films are significantly influenced by the silane coupling agent used by Coace, which is an essential ingredient in the creation of these films.
By enhancing their physical and chemical characteristics, silane coupling agents can improve the performance of solar photovoltaic films. In particular, silane coupling agents can strengthen the mechanical strength and impact resistance of solar photovoltaic films while also increasing their adhesion, chemical and weather resistance. As a result, silane coupling agents are frequently employed in the solar photovoltaic film manufacturing process.

 

4. Silane coupling agents’ potential for use in the solar photovoltaic industry

Silane coupling agents have seen constant expansion in their application in the solar photovoltaic business, which has grown at a rapid pace. Silane coupling agents are now one of the most important raw ingredients used in the manufacturing of solar photovoltaic films. Silane coupling agents, which can significantly increase the stability and conversion efficiency of solar cells, are also frequently utilized in the manufacturing process of solar cell modules. As a result, silane coupling agents have a large market and promising future development in the solar photovoltaic sector.

 

 

In summary, silane coupling agent is an essential component used in the manufacturing of solar photovoltaic films. Silane coupling agents have the potential to increase solar photovoltaic films’ adhesion, stability, and resistance to water, humidity, and UV light. It has very strict standards for the product’s purity and trace ion residue in addition to its high efficiency and easy application method. Although the ions will boost the material’s conductivity, they will also shorten the membrane material’s service life and aging resistance. Silane coupling agents therefore offer a wide range of potential applications in the solar photovoltaic sector. A silane-grafted POE photovoltaic encapsulating film masterbatch is COACE’s R1020. High silane content, no precipitation, no water absorption, good dispersion, good stability, high transparency, and good weather resistance are some of this product’s features.
