Graphene is hailed as the most revolutionary material of the 21st century, earning the title of "king of new materials" due to its exceptional properties. Composed of a single layer of carbon atoms arranged in a honeycomb lattice, graphene exhibits a range of remarkable physical characteristics. It is 100 times stronger than steel and has excellent electrical conductivity, with its carrier mobility at room temperature being approximately 10 times that of silicon. Additionally, graphene boasts outstanding thermal conductivity, with a thermal conductivity coefficient of up to 5300 W/mK, far surpassing most materials. Graphene is also nearly transparent, with an absorption rate of just 2.3% in the optical range. It retains excellent flexibility, allowing it to bend and deform while maintaining its structural integrity. These unique properties make graphene a material of enormous potential across various fields and are widely believed to herald a materials revolution.
As technology has advanced, the applications of graphene have increasingly permeated various industries. In electronics, graphene is used to manufacture ultra-high-frequency chips and the next generation of heat-dissipation materials. In energy storage, it is applied in high-performance batteries such as fast-charging and power batteries. Graphene batteries have already been validated in two-wheel electric vehicles, significantly improving charging speeds and extending battery life. Moreover, graphene has been utilized in anti-fog goggle coatings, anti-corrosion coatings for deep-sea engineering and offshore wind power facilities, and functional clothing with UV resistance, enhanced microcirculation, and antibacterial properties.
In the solar energy sector, graphene's application is particularly prominent, significantly boosting the efficiency and lifespan of photovoltaic (PV) modules. Graphene anti-reflection coatings can improve the light transmittance of solar glass by 0.5% to 1%, increasing module power by 2-3W. Furthermore, graphene coatings exhibit superhydrophilicity and photocatalytic properties, which effectively decompose organic pollutants, helping to keep the glass surface clean. This reduces dust accumulation, which can otherwise lead to a decrease in power generation and the development of hot spots. The self-cleaning function reduces maintenance costs and extends the lifespan of the modules.
Currently, all module models developed by ZNSHINE Solar can be equipped with graphene technology. As the first company in the industry to apply graphene patent technology to the mass production of PV modules, ZNSHINE Solar has significantly enhanced the power generation efficiency of its modules through this technology, while also delivering substantial maintenance cost reductions for its customers.
Field tests have shown that PV modules equipped with graphene technology deliver an average energy yield gain of about 2%. This not only boosts power generation performance but also enhances the safety and reliability of the system, while reducing production and maintenance costs. More importantly, graphene technology can seamlessly integrate with existing PV technologies, such as PERC and black silicon, providing a fresh impetus for innovation and advancement in the solar industry.
As a revolutionary material, graphene is transforming production and life across numerous industries. From electronics to renewable energy, from aerospace to marine engineering, graphene’s applications continue to expand. In the solar sector, graphene provides a new solution for improving solar energy utilization and reducing system costs. As research deepens and the technology becomes increasingly commercialized, graphene is set to play an ever more critical role in the development of the global clean energy industry, driving technological innovation and progress.

When purchasing solar modules, performance and price are the two key factors to consider. The performance of a solar module depends not only on its photovoltaic conversion efficiency but also on the strength and durability of its structure. As a crucial support and protective component, the frame material has a direct impact on the overall performance of the module. Additionally, solar module frames, being high-value auxiliary materials, play a significant role in the module’s total cost structure. For instance, *the commonly used aluminum frame, with its strong mechanical properties, accounts for around 13% of the total module cost—surpassing other auxiliary materials like EVA, glass, backsheets, and solder ribbons—second only to the 55% cost share of the solar cells themselves.
Installing a solar photovoltaic (PV) system on a roof is a crucial process that requires ensuring the system efficiently captures solar energy while maintaining its safety and stability. This article will describe how to use the SRS (Solar Racking System) to install PV modules more securely and efficiently.
Una célula fotovoltaica es algo relativamente sencillo.

The first bifacial photovoltaic cells were created in the laboratory several decades ago. The first company that commercialized them was the Spanish company Isofoton (1981), based on the studies of Antonio Luque at the Institute of Solar Energy in Madrid.Today’s bifacial solar modules are a simplifi
Double glass photovoltaic modules stand out with remarkable advantages in power generation, embodying authenticity in their performance. The transparency and robust UV resistance of glass seamlessly align with the characteristics of double-sided cells, establishing a flawless synergy. When it comes to the module backsheet, the industry widely acknowledges the superiority of glass backsheets. In 2018, Joshua S. Stein from Sandia National Laboratories and Dirk C. Jordan from the National Renewable Energy Laboratory (NREL) conducted an in-depth review of double glass photovoltaic modules, delving into various pertinent issues.
