1. Comparison of PVB Photovoltaic film and EVA Photovoltaic film:
EVA is a thermosetting resin with cross-linking reaction; PVB is a thermoplastic resin with reproducibility and no cross-linking reaction;
The domestic glass curtain wall specification clearly puts forward the regulation of "application of PVB". BIPV photovoltaic modules can be made by PVB instead of EVA to achieve a longer service life. PVB Photovoltaic film making machine
PVB has strong adhesive properties, and its safety is higher than that of EVA Photovoltaic film;
EVA has many formulas, and the packaging process is not easy to control; the formula of PVB film is simple, the quality control is stable, and the shelf life is long;
PVB film has poor fluidity, which can prevent film overflow during processing.
At present, the packaging forms of photovoltaic modules mainly include glass-EVA-backsheet and glass-PVB-glass. I will describe the characteristics of EVA and PVB encapsulation films respectively.
Photovoltaic industry is a rapidly developing emerging industry that converts solar energy into electric energy. Silicon solar cell modules are mainly used in large-scale grid-connected power generation, off-grid power stations, BIPV photovoltaic building integration, etc. The encapsulation films mainly include EVA and PVB.
