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.

Electrical connection materials are crucial components in photovoltaic (PV) modules for achieving current conduction, and their performance directly impacts the module's conductive efficiency, reliability, service life, and safety. The following analysis explores the specific impacts of core materials such as solder ribbons, busbars, and junction boxes on module performance :

Photovoltaic junction boxes are crucial components in PV modules for connection and protection. Integrated ones have a simple structure with one box housing diodes and cables, offering low - cost and easy installation. However, they face heat - dissipation and resistance issues in high - power applications. Split - type junction boxes consist of multiple boxes, each with one diode and separated positive/negative cables. They have excellent heat - dissipation, can boost module power and reduce cable usage, yet are costlier and require more complex installation. The former suits small - scale distributed projects, while the latter is more suitable for large - scale ground - mounted power plants.

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'.

Light transmittance serves as the critical differentiator between BIPV (Building-Integrated Photovoltaics) and conventional PV modules, directly governing the tripartite balance of architectural daylighting, aesthetic integration, and power generation efficiency. By 2025, cutting-edge technologies enable fully customizable transmittance (10%-70%), tailored to diverse application scenarios.

In 2025, photovoltaic new materials such as perovskites, organic photovoltaics, and quantum dots are driving industry transformation. Perovskite solar cells have achieved efficiencies exceeding 25% and entered mass production, with a projected 10% market share within three years. Organic photovoltaic materials have been commercialized, advancing the flexible electronics market. Quantum dot materials are widely used in high-efficiency solar cells, with breakthroughs in non-toxicity accelerating their commercialization. Two-dimensional materials like graphene have boosted module efficiency by 15%. Global photovoltaic installed capacity is expected to reach 1,500 GW. Supported by policies and technological innovation, these new materials are accelerating commercialization and driving the global transition to clean energy.

In recent years, the solar roof industry has witnessed remarkable growth, driven by advancements in technology, increasing environmental awareness, and supportive government policies. Solar roofs, which integrate photovoltaic (PV) panels into roofing materials, are revolutionizing the way we generate electricity while providing a sustainable solution to energy consumption.

The news highlights the booming prospects of the photovoltaic glass industry. As a key component in solar power systems, photovoltaic glass, known for high light transmittance, mechanical strength, and weather resistance, is crucial for solar cell protection and power generation efficiency. Driven by the global push for carbon neutrality, the solar photovoltaic industry's growth, with over 20% annual capacity increase expected, fuels the market.

Perovskite is a material with a unique crystal structure. As a representative of the third-generation solar cells with low cost and high photoelectric conversion efficiency, perovskite solar cells have great application potential.

What are photovoltaic materials? The materials used to produce solar panels or cells that convert sunlight into electricity are known as the photovoltaic materials market. These materials are primarily semiconductors that absorb light and convert it into electrical charges. Perovskite, organic and silicon-based photovoltaic materials are the most widely used types of photovoltaic materials. Silicon-based photovoltaic materials dominate due to their efficiency, reliability and proven production methods. However, new technologies such as perovskite solar cells are beginning to emerge as possible industry game-changers because they can deliver higher efficiencies at a cheaper cost. Traditional solar panels are not the only photovoltaic materials on the market. The uses of solar energy are also expanding thanks to advances in solar thin films, bifacial solar cells and building-integrated photovoltaics (BIPV).
