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.

Perovskite is A material with a unique crystal structure, originally found in natural minerals, and now generally refers to a class of compounds with the structure of ABX3, where A is usually an organic cation, B is a metal ion, and X is a halogen anion. This structure gives perovskite materials a series of excellent photoelectric properties, so that they show great application potential in the field of solar cells. Perovskite materials can adjust the band gap by changing the composition of the material, and then regulate the wavelength range of the light absorption, and maximize the utilization efficiency of sunlight. It is precisely because of the adjustable band gap of perovskite materials, when constructing solar cells, perovskite materials with different band gaps or perovskite materials and silicon-based materials can be composed of laminated structures to improve the overall light absorption efficiency. In addition, perovskite materials can be prepared at low temperatures by wet process such as solution method, and the preparation cost is also low. As a representative of the third generation solar cells with low cost and high photoelectric conversion efficiency, perovskite solar cells have great application potential.

Photovoltaic (PV) adhesives utilize moisture in the air to cure at room temperature to provide excellent bonding and sealing properties for solar PV module outer frame and junction box applications. When manufacturing and assembling PV modules, it is necessary to select adhesives with excellent properties such as high light transmission, weatherability, and high adhesion to ensure the quality and long-term stability of PV modules. The importance of adhesives in PV modules is mainly reflected in the following aspects:

Photovoltaic glass plays an important role as the special glass for the cover plate of solar cells It not only protects the solar panel from oxidation and corrosion by external moisture and gas, but also ensures that the components are not subjected to external forces The core performance of photovoltaic glass lies in its high transmittance, high strength and strong corrosion resistance These characteristics directly affect the life and power generation efficiency of photovoltaic modules.

According to the "Global PV Market Outlook for the first Quarter of 2024" report released by PV-Tech, the global PV installed capacity will increase from about 444GWdc in 2023 to 655GWdc this year. China will continue to dominate the installed capacity in 2024 (313.7GWdc), accounting for 54.7% of the new global PV capacity installed this year. It was followed by the United States (40.6GWdc), India (18.1GWdc), Brazil (17GWdc) and Germany (16.5GWdc).

China's installed solar capacity reached 360GW at the end of October 2022, a 29% increase year-on-year, according to figures from the country's National Energy Administration.

The cell is generally divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon solar cell is one of the fastest developed solar cells at present. Its structure and production process have been finalized, and the products have been widely used in space and ground. The solar cells are made of high purity monocrystalline silicon rods.

According to the latest market report, the solar photovoltaic glass market size is expected to grow from USD 6.2 billion in 2022 to USD 21.1 billion in 2027, representing a CAGR of 27.9%. During the forecast period, Asia Pacific is expected to have the largest market size in the global solar photovoltaic glass industry. AR coated solar photovoltaic glass holds the largest share in the global solar photovoltaic glass market during the forecast period. Especially in China. According to the International Energy Agency, the Asia-Pacific region has a 90% share of solar module manufacturing, and China alone accounts for 74% of the global manufacturing capacity. These glass are mainly used in solar modules, so the glass demand in this region is the highest.
