PV ribbon is a specialised joining material for solar modules, which can be subdivided into a number of different varieties and types according to different needs and applications. Below are some of the main varieties and types of PV ribbon:
Tinned Copper Solar Ribbon: Copper-based PV ribbon is usually made of copper foil with a tin-covered surface for improved corrosion resistance. This type of ribbon is used for cell attachment at the front and back of the solar cell, and is usually suitable for single-sided solar cells.
Aluminum Solar Ribbon: Aluminum-based PV ribbons are made of aluminium foil and are typically used for double-sided power generation applications such as BC PV cells. They have good electrical conductivity and corrosion resistance and are suitable for a wide range of environmental conditions.
Silver Solar Ribbon: Silver-based PV ribbons typically have excellent electrical conductivity and are therefore more widely used in high-efficiency solar cells. They reduce resistive losses and improve cell performance.
Double-Sided Solar Ribbon: These PV ribbons are used in BC PV cells and can be attached to the front and back of the cell to improve energy conversion efficiency.
Reflective Solar Ribbon: Reflective ribbons usually have a special reflective coating that increases the ability of the solar module to absorb sunlight. This helps to increase the efficiency of the cells.
Flexible Solar Ribbon: These PV ribbons are usually made of flexible materials and are suitable for connecting curved or flexible solar modules. They can be adapted to different shapes and designs.
Custom Solar Ribbon: Some manufacturers offer customised PV ribbons to meet the needs of specific projects or modules. These ribbons can be customised according to design requirements.
Standard Solar Ribbon: This is the most common type of PV ribbon and is suitable for general solar modules with standard specifications and performance.
These different types of PV ribbons can be selected based on the project requirements and the type of solar cell. Choosing the right PV ribbon is critical to ensuring the performance and reliability of the module.
