Photovoltaic PVB
Product Classification:
Product Introduction
Photovoltaic PVB intermediate film as a photovoltaic module packaging material, with high light transmittance, low resistivity, aging resistance and other product characteristics, compared with EVA, POE and other traditional packaging materials can significantly extend the service life of double-glass photovoltaic modules (BIPV) and improve module power generation efficiency.
