Grafeno y tecnología autolimpiante: aplicación en módulos fotovoltaicos
¿Qué es el Grafeno?
El Grafeno, conocido también como « el material milagroso » por sus muchas cualidades, fue descubierto hace casi un siglo. Está formado por una lámina de carbono puro en la que los átomos se unen como en un panel de abejas. Esta lámina es un millón de veces más fina que una hoja de papel.
¿Pero por qué le llaman el material milagroso?
El Grafeno es extremadamente ligero; es transparente; más flexible que la fibra de carbono; impermeable; no contamina; es más duro y fuerte que el diamante y el acero y es 100 veces mejor superconductor que el silicio que usamos en los actuales micro-procesadores.
Módulos fotovoltaicos ZNSHINE Solar con vidrio con grafeno.
La tecnología de vidrio con recubrimiento de Grafeno, aplicable a cualquier módulo fotovoltaico, es resultado de los avanzados desarrollos de ZNSHINE Group y la Universidad de Ciencia y Tecnología de China.
El vidrio con recubrimiento de Grafeno, desarrollado por ZNSHINE Solar, ha superado las exigentes pruebas realizadas en laboratorios externos autorizados y bien conocidos a nivel mundial, permitiendo que desde 2018 ZNSHINE Solar haya comercializado en el mercado fotovoltaico mundial el primer módulo autolimpiable con las mejores garantías, ofreciendo Alta Tecnología de Confianza a sus clientes.
ZNSHINE Solar aplica el Grafeno integrado en el vidrio frontal del módulo, y no como un recubrimiento superficial. Esta solución manufacturada de forma industrial garantiza la homogeneidad y durabilidad de las ventajas del Grafeno.
¿Y cuáles son sus características y ventajas?
Atractivo retorno sobre la inversión gracias a que el panel siempre está más limpio. Esto es debido a que sus excelentes propiedades hidrofílicas permiten que el polvo se limpie rápidamente con la lluvia sin aguas residuales en superficie evitando el “soiling”
Mejora la capacidad de generación de energía de todo el sistema como mínimo en un +2% gracias a su mejorada transmisión de la luz al interior del módulo. Valor que se ha visto incrementado hasta un 4-5% en mega proyectos durante operación continua de más de 6 meses
Reduce el costo de mantenimiento al minimizar las tareas de limpieza
Reduce el riesgo de puntos calientes que son causados por sombras puntuales cuando la suciedad se mantiene de forma prolongada
Autolimpieza de los residuos más resistentes por efecto fotocatalítico: Rápida descomposición de los contaminantes orgánicos
Mayor durabilidad: El vidrio es más resistente a impactos y arañazos gracias a la dureza del Grafeno
Graphene coating and self-cleaning technology in PV modules
What is Graphene?
Graphene, also known as “the miracle material” for its many qualities, was discovered almost a century ago. It is made of a sheet of pure carbon in which the atoms come together as in a panel of bees. This sheet is a million times thinner than a sheet of paper.
Why is it known as “the miraculous material”?
Graphene is extremely light; it’s transparent; more flexible than carbon fiber and waterproof. It does not pollute, it is harder and stronger than diamond and steel and is 100 times better superconducting than the silicon we use in today’s microprocessors.
ZNSHINE Solar photovoltaic modules with Graphene-Coating glass
The Graphene-Coating glass technology, applicable to any photovoltaic module, is the result of advanced developments by ZNSHINE Group and the University of Science and Technology of China.
Graphene-Coating glass, developed by ZNSHINE Solar, has passed the demanding tests carried out in authorized and well-known external laboratories worldwide, allowing ZNSHINE Solar to market the world’s first self-cleaning module with the best guarantees since 2018 on the global photovoltaic market, offering High Trust Technology to its clients.
ZNSHINE Solar applies the Graphene integrated with the front glass of the module, and not as a surface coating. This industrially manufactured solution guarantees the homogeneity and durability of the benefits of Graphene.
What are its characteristics and main advantages?
Attractive return on investment thanks to the fact that the panel is always cleaner. This is due to the fact that its excellent hydrophilic properties allow the dust to be cleaned quickly in the rain without residual water on the surface, avoiding “soiling”
It improves the power generation capacity of the entire system by at least + 2% thanks to its improved light transmission inside the module. The value that has been increased up to 4-5% in mega projects during continuous operation of more than 6 months
Reduces maintenance cost by minimizing cleaning tasks
Reduces the risk of hot spots that are caused by spot shadows when the dirt is maintained for a long time
Self-cleaning of the most resistant residues by the photocatalytic effect: Rapid decomposition of organic pollutants
Greater durability. The glass is more resistant to impacts and scratches thanks to the hardness of Graphene

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.
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.
