Graphene: A Revolutionary Material Enhancing Solar Efficiency and Durability

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.

Advances in Solar Module Frame Technology: A Comparative Analysis of Materials

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.

Tecnología PERC, cambio en la arquitectura de la célula

Una célula fotovoltaica es algo relativamente sencillo. Un material semiconductor, en el que se ha creado un diodo (se le ha dado polaridad), al que se le pone una capa azul antirreflejante y se conectan unos conductores eléctricos para extraer la electricidad. Digamos que la arquitectura de la célu
