As a key product of the third-generation photovoltaic technology, perovskite transparent modules have distinct advantages. They balance 20%-50% customizable light transmittance with over 20% energy conversion efficiency. Prepared via low-temperature solution processes, they have lower production costs. Available in rigid and flexible types, they adapt to diverse scenarios like buildings and vehicles. They also block over 99% of UV rays, with green production, supporting energy conservation and carbon reduction in construction.

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.

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.

POE film is in a multi-driven cycle of technological breakthroughs, domestic substitution, and global expansion. In the future, it is necessary to focus on core technology R&D and supply chain independence, and address the competition from alternative materials and industry risks, in order to maintain a dominant position in the photovoltaic packaging material market.

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.
