1. A flexible print circuit board (FPCB)/flexible copper clad laminate (FCCL) replacing a tinned-copper welding strip as a photovoltaic module bus bar, wherein the FPCB/FCCL is a composite material comprising an insulating base material and a conductive layer, and the insulating base material is made from polyimide (PI) or polyethylene terephthalate (PET), wherein
the FPCB/FCCL comprises a composite of copper foil with the PI or the PET as an organic material,
a first part of the copper foil of FPCB/FCCL comprises a circuit and a second part of the copper foil does not comprise a circuit, and
the FPCB/FCCL is configured for use in a flexible solar module requiring repeated flexure by resisting becoming fatigued and fragile and avoiding fracture and opening of the circuit.
