Solar drip glue panels have expanded applications from traditional outdoor lighting and small electronics to distributed PV, portable energy, BIPV, and special scenarios. The industry will advance toward high-performance materials, intelligent manufacturing, green products and diversified applications, with significant market growth potential. Customized demand is rising, and green environmental protection (e.g., bio-based resins, degradable encapsulation) will be the core direction, supported by policies. It will play a more important role in global energy transition.

The core application scenarios of two-component silicone adhesives are "structural bonding + long-term reliability requirements". They focus on core components of PV modules (such as frames and junction boxes) and connection parts between BIPV modules and building structures, making them particularly suitable for applications involving large-size modules, heavy loads, and extreme environments. Their selection must match module materials (glass, aluminum, backsheets), service environments (temperature, humidity, UV radiation), and mechanical requirements (bonding strength, displacement capacity). They are key materials ensuring the safe operation of PV modules and BIPV systems.

Perovskite PV modules have achieved a 22% mass production efficiency, on par with crystalline silicon modules. Single-junction and perovskite/crystalline silicon tandem technologies advance in parallel, with the latter’s R&D efficiency hitting 34.85%. China has built multiple GW/100MW-level production lines, with 50MW sales expected in 2025. Its low cost and flexibility suit BIPV, with 20GW global shipments projected by 2030.

In 2025, the "solar-storage duo" of solar panels and batteries has gone mainstream, evolving from professional gear to daily energy stewards. Thin, flexible, and easy to install, they power homes (balconies as mini power stations), camping trips, remote areas, and even desert restoration. Boosted by perovskite and sodium-ion tech, they're smarter, more cost-effective, and eco-friendly, enabling energy independence and supporting global decarbonization.

In the critical period of PV modules transforming towards "higher efficiency, longer service life, and better scenario adaptation", the selection of solar ribbons has changed from "passive adaptation" to a core link of "active optimization". Enterprises with full-specification solar ribbon supply capabilities and customized services can help module enterprises establish a "battery technology - power target - application scenario" trinity selection system, fully unlock the performance potential of modules, and provide solid supply chain support for the goal of grid parity in the PV industry.

The thickness of ETFE (ethylene-tetrafluoroethylene copolymer) — ranging from 25μm to over 1mm, with composite structures reaching the millimeter level — directly determines its mechanical properties, light transmittance, etc. It is divided into three types for PV and other fields: Ultra-thin (25-50μm): Extremely lightweight, highly flexible, ~95% light transmittance, suitable for flexible PV encapsulation and portable energy equipment; Conventional (50-200μm): Balanced performance, accounting for over 70% of global consumption, used in BIPV membrane structures and rigid PV protection; Thick-walled/composite (200μm+): High strength and corrosion resistance, applied in PV power plant protection, industrial linings and special building load-bearing structures.

Self-adhesive flexible solar modules offer key advantages: easy installation without brackets/drilling, cutting steps by 70% and boosting efficiency by 40%; adaptability to curved/irregular surfaces; lightweight (4-5kg/m²) for load-sensitive areas; reduced base material damage and waterproof risks; suitability for temporary/mobile use. Disadvantages include limited durability (affected by temperature/UV), high temperature sensitivity, hard maintenance/replacement, strict base material compatibility, and cost-performance conflicts.

Greenhouse solar modules show bright prospects. With strong demand, they solve energy issues in agriculture. Technological innovations like spectral filtering boost efficiency. Policy support drives growth, aiding energy transition and agricultural development.

On June 10, the 18th (2025) International Solar Photovoltaic and Smart Energy & Energy Storage and Battery Technology and Equipment (Shanghai) Exhibition opened at the National Exhibition and Convention Center (Shanghai). Over 3,600 companies from 95 countries showcased products spanning the entire photovoltaic industry chain. Advanced technologies like TOPCon and perovskite tandem cells, along with integrated photovoltaic - energy storage solutions, were highlights. The event also featured forums on industry trends. Lasting until June 13, this exhibition serves as a crucial platform for global cooperation, innovation, and the push towards green energy transition.

This article focuses on the advantages and disadvantages of double - sided and single - sided coated fluorinated backsheets for photovoltaic modules. Double - sided coated ones offer excellent weather resistance, high mechanical strength, and good compatibility, but they are costly, less environmentally friendly, and heavy. Single - sided coated backsheets have cost and weight advantages, and better environmental performance, yet their weather resistance is slightly weaker, the process is more complex, and market recognition is low. Overall, the choice between them depends on specific project requirements and application scenarios.
