metallic conductor on the front or back of a PV cell intended to conduct the electric current generated by the PV cell
NOTE 1 A metallisation line can be screen-printed, vapour-deposited or extruded (line-written)
The lines are of two types
a) bus bar (of photovoltaic cells)
metallisation line with a cross-section area greater than that of the grid lines, connected to grid lines and intended to carry their electric current to the wires or ribbons interconnecting the PV cell with other PV cells
NOTE 2 Interconnect wires are connected to the bus bars by soldering or welding
b) grid line
metallisation line intended to collect electric current from the surface of the semiconductor of the PV cell |
