Grid Lines Definition. Known as busbars or finger lines, they are thin conductive lines that are applied to the surface of solar photovoltaic (PV) cells. These lines play a critical role in facilitating the flow of electric current generated by sunlight-absorbing cells, enabling the conversion of solar energy into usable electricity.
