SOLAR ENCAPSULATION MARKET SEGMENTATION

By Type

Based on Type, the global market can be categorized into Ethylene Vinyl Acetate (EVA), Polyvinyl Butyral (PVB), Polydimethylsiloxane (PDMS) & Ionomer

• Ethylene Vinyl Acetate (EVA): EVA is the topmost material in the most extensive solar encapsulation market as regards excellent optical transparency and adhesive properties. Protection against the environment, such as UV radiation, moisture, and mechanical stress, ensures that solar panels have a longer lifespan. EVA encapsulants are low cost and compatible with several photovoltaic technologies, which is the main reason they get favor from manufacturers. The yellowing phenomenon has created research on novel materials and improved formulations, which pose a challenge.

• Polyvinyl Butyral (PVB): It is transparent, flexible, and has a great degree of adhesion. It is usually utilized in buildings integrating photovoltaics (BIPV) because it provides structural stability with good aesthetics. The encapsulation enables a good deal of flexibility and durability with remarkable properties against UV degradation. But it is expensive compared to EVA and not suitable for very moist conditions; hence, their widespread use in conventional PV modules is limited.

• Polydimethylsiloxane (PDMS): PDMS is the silicone material that provides thermal stability, elasticity, and resistance to environmental stresses in a superior way to other variables. Unique properties, such as lighting having wavelengths between the ultraviolet and visible range, well suited for suitable, flexible, and high-efficiency PV, include developing fine features in thin-film technologies. Minimal optical losses, along with long-term performance under harsh conditions, are also achieved from PDMS encapsulants. However, the production cost is higher, which would work as an impediment towards mass adoption in the solar industry.

• Ionomer: These optical and water vapor permeation characteristics combined with their extreme mechanical strength and delamination resistance make these emerging materials most preferred for solar encapsulation. High optical clarity and low water vapor permeability are thus two characteristics that improve the performance and durability of the PV modules. Among bifacial solar panels, these ionomer encapsulants are favored mainly due to their capability to endure extreme environmental conditions. However, the ionomer's price is more than that of EVA, hence restricting it to premium or specialized solar applications.

By Application

Based on application, the global market can be categorized into Automotive, Construction & Electronics

• Automotive: In the automotive segment, solar encapsulation is fast growing, where solar panels are installed in the electric and hybrid types of vehicles to improve energy conversion. Encapsulation assures durability and protection of PV cells from vibrations, temperature changes, and environmental weather conditions. Lightweight and flexible encapsulants are preferred, thereby enabling the meeting of design and weight criteria of vehicles. This is driving great innovations in solar technology, especially for autonomous energy generation in vehicle.

• Construction: Solar encapsulation emerges in this construction industry's building-integrated photovoltaics (BIPV) and building-applied photovoltaics (BAPV) applications for energy-efficient buildings. Encapsulation materials become significant for the durability, transparency, and aesthetics of solar panels for windows, facades, and rooftops. These materials also protect against radiation of UV from moisture and structural stress, helping performance last over the long term. With the sustainable construction trend, encapsulants formulated for architectural applications are experiencing widespread adoption.

• Electronics: Solar encapsulation mainly focuses on small and portable solar energy devices, such as chargers, sensors, and wearable technologies, for electronics. Encapsulation materials make the solar cells durable and effective under outdoor conditions like moisture, UV radiation, and changes in temperature. In addition, the importance of flexible and lightweight encapsulants prominently features in the integration of solar panels into small and portable electronic devices. The segment is currently benefiting from ongoing progress in thin-film and flexible PV technology, which promotes innovation in encapsulation materials.
