A typical c-Si solar PV module is made up of several silicon (Si) cells connected in series, which are the key components of the module. The cells are encapsulated between two sheets of polymer (EVA − Ethylene Vinyl Acetate) and a front glass on top and a backsheet, which is a combination of polymers (PET: Polyethylene terephthalate and PVDF:
Fourthly, during the welding process, remember to straighten the welding strip to ensure that it is straight and completely covers the printing line of the solar cell, without causing white exposure. Through the above measures, it is possible to effectively reduce the probability of EVA glue deficiency, insolubility, and photovoltaic ribbon offset.
