“PV” is an acronym for Photo Voltaic, meaning something that produces current when struck by a molecule of natural light. Solar photovoltaics is a booming technology these days, with so many environmental concerns being raised be conventional sources of energy. The genius combination of solar photovoltaic materials and harnessing energy has made it possible to convert sunlight into electricity on a large scale. The PV ribbon wire is a very important component of photovoltaics. This blog will give you in-depth knowledge about PV ribbon wire.
What is PV ribbon?
Typically, a photovoltaic ribbon is a thin strip of copper which is heat coated with tin. This is the wire which is used to connect solar cells together in a solar module. The photovoltaic ribbon is attached directly to the silicon substrate on a solar cell, which enables it to collect the electricity produced in the cell. These PV ribbons then connect to the PV bus bar. In this manner, the current generated in the solar cells connected with one PV ribbon is sent to the PV bus bar. PV bus bar is also a PV ribbon which is slightly bigger than the interconnect ribbon used with solar cells.
Technical details of PV ribbon
The PV ribbon used as bus bars are about 3 to 6mm wide and 0.2 to 0.5mm thick, while those used for interconnection of solar cells are 1 to 3mm wide and 0.08 to 0.2mm thick. If you went out to buy one, you would typically find spools weighing anywhere between 50kg to 600kg. They contain tin (100%) as the lead free solder option, and SnPb 60/40 as the leaded option. You can find these ribbons in low temperature versions as well with Bismuth in the alloy.
Above are the major points you need to know about PV ribbon.
