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'.

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.

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).
