Description

  Double-glazed PV module refers to: the PV battery pack is formed by two pieces of tempered glass, EVA film and solar cell silicon wafer laminated by the laminator under high temperature to form composite layer, with the connection in series or in parallel the cells via guide line to the end of lead. It comprises tempered glass in the first layer, PVB/PO/EVA/ionic polymer in the second layer, monocrystalline or polycrystalline battery pack in the third layer, PVB/PO/EVA/ionic polymer in the fourth layer and tempered glass or high-transmittance backboard in the fifth layer, which are set from the top to the bottom.
