Photovoltaic ribbon, also known as solar cell ribbon or solar panel ribbon, is a crucial component in the manufacture of solar panels. It is a flat, thin strip of conductive material that connects solar cells together to form an electrical circuit. The most common materials used for photovoltaic ribbon are copper and silver.

Tinned copper interconnects also known as Tabbing Ribbon, Solar Wire, Cell Connector, String Connector, PV Ribbon, PV Connect etc. are conductive components made from copper that has been coated with a thin layer of solderable alloys made from various metals such as silver, tin, lead, indium, etc.
Results show that improved ribbon reflectance or geometry can enhance module performance by 0.7%. However, the combined effect of better reflectance and geometry can increase the power of a module by 1.6% and the energy yield per area by 1.5%.
The distance between the coil and the surface of the metal ribbon on top of a solar cell is an important parameter in this experimental work because the magnetic field strength and direction highly depend on the distance. Three distances (2.0 mm, 3.0 mm, and 4.0 mm) were selected to observe how the change in distance affects the heating and ensures the …

The best solar cells fabricated on such N-type Si RST ribbons and plasma hydrogenated exhibit efficiencies of about 12.4% with boron-spin-coating emitter and 13.5% for boron ion-implanted emitter. The cell performances are still suffer from a low open circuit voltage and fill factor due to non-optimized emitter and contacts resistances.

The process is continuous. Chunks of silicon enter the furnace and melt, the strings unwind from spools, and the emerging ribbon is cut to 2-meter lengths without stopping. Each ribbon is then laser-cut into wafers, which go directly onto a belt for the next step in becoming solar cells and ultimately high-efficiency solar panels.
