The quality of the silicon wafer directly determines the conversion efficiency of solar cells. An electroluminescence (EL) flaw detector shown in Fig. 1 is used to judge whether solar cells are defective [2]. The solar cell is excited by a forward current of 1–40 mA, and the atoms in an excited state are unstable.
Effect of PV welding strip on the welding process of solar cells. A large number of solar cells are connected in series through PV welding strip at a certain temperature, thus obtaining larger output power. Generally, before welding, the worktable is heated to 50–60°C and the constant temperature electric iron is heated to 380°C.
