Since 2026, all-black solar modules have become a core choice in residential, distributed and BIPV scenarios, with rising penetration. They boast integrated pure black design, high efficiency (23.5%-25%+ conversion rate), double-glass & POE/EPE packaging for reliability, and fit high-end buildings. As a key product line of Xindongke, they are in high demand in Europe and North America, with broad prospects as technology advances and market expands.

For flexible solar panels, front sheet selection is important. Main materials: ETFE (high-end, 92%-95% transmittance, 20-30-year life), PET (budget, short-term use), composite fluorine film (mid-range), enhanced types (flexibility+strength). Choose based on scenario and cost balance; ETFE and reinforced types will dominate future market.

Silicone sealant, a polymer with adhesion, sealing, weather resistance and insulation, has multiple types. It's widely used in construction, photovoltaic, electronics, automotive, aerospace, medical and marine fields for bonding and sealing.

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.

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.

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.

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.

By 2025, the development of flexible photovoltaic technology will focus on three core breakthrough directions: In the materials field, efforts will concentrate on improving the environmental stability of perovskite components and developing lead-free processes, while also exploring new quantum dot composite structures to enhance photoelectric conversion efficiency. In terms of manufacturing processes, advancements will be made in intelligent roll-to-roll precision printing technology and multi-material layer integration to achieve more efficient and cost-effective large-scale production. For application innovation, special flexible components suitable for extreme environments will be developed, equipped with interactive functions such as smart dimming and health monitoring, along with establishing a sustainable material recycling system. This will drive the transformation of flexible photovoltaics from a single power generation function to an intelligent, scenario-based 'energy skin'.
