This article explains why solar panels are often referred to as the "blue ocean". Solar panels are mainly divided into polycrystalline (blue) and monocrystalline (black) types. Polycrystalline panels adopt the casting process; light scattering at grain boundaries and optical interference of anti-reflective coatings give them a blue hue. As an early photovoltaic technology, their power generation efficiency is generally below 18%. Monocrystalline panels are made via the Czochralski method with a neat crystal structure. Optimized production processes make them look deep black, and they have become mainstream since 2019 with an efficiency of over 23%. People can tell the two types apart by front-side colors, while the back of bifacial monocrystalline panels still appears blue due to the absence of textured surfaces. Read More

This article focuses on the four core structures of PV panel cells—grid lines, PAD points, MARK points, and forked notches. It elaborates on their respective definitions, structural characteristics, and core functions: grid lines serve as the "current collection and transmission network" to collect and transport photogenerated electrical energy; PAD points act as the "connection bridge" between cells and ribbons, enhancing conductivity and welding strength; MARK points function as the "positioning benchmark" for cell printing, ensuring the accuracy of grid line printing; forked notches are the "chip-resistant protection design" to avoid cell chipping and microcracks during processing. The article points out that these four tiny structures cooperate with each other, forming the foundation for the efficient and stable operation of PV cells, and reflects the importance of detailed design in the iteration of photovoltaic technology.

Europe, once heavily dependent on Chinese photovoltaic products amid the energy crisis, has shifted to stringent regulatory restrictions. France embedded strict supply chain rules into its latest PV tender, restricting assembly and core PV components from a targeted third country. The EU has escalated curbs from tariffs and public opinion to hard institutional constraints on bidding, funding and subsidies, with limits expanding across member states and related energy projects. As Europe blocks third-country transshipment and low-cost competition, Chinese PV enterprises must abandon simple overseas OEM, advance in-depth local manufacturing, and shift from product sales to integrated solar-storage solutions. Meanwhile, the new rules force the domestic PV industry to escape price involution and upgrade technological, system integration, brand and global operation capabilities. Read More

Under the global energy structure transformation towards cleanness and intelligence, SMES, the core of electromagnetic energy storage, has obvious advantages such as high efficiency, fast response and excellent regulation compared with mainstream energy storage technologies, and is expected to expand applications to support new power systems and "dual carbon" goals despite current technical limitations.
