Photovoltaic module laminated non-woven board

How are PV modules laminated?

The lamination of PV modules is most frequently carried out using a vacuum-membrane laminator with a single heating plate (Fig. 5) and a typical process based on three main steps .

How can a lightweight PV module be made?

In a previous work , it was demonstrated the possibility to produce a lightweight PV module with a weight of 5 kg/m 2, by substituting the typical front glass with a thin polymer sheet and the standard backsheet by a composite sandwich structure.

What is a PV module architecture?

The developed module architecture is based on a composite sandwich backsheet and a polymeric frontsheet. In order to allow an efficient process using conventional lamination lines used by the PV industry, the composite sandwich backsheet is assembled using encapsulant foil instead of a liquid epoxy.

Can a lightweight PV module withstand the harshest IEC aging tests?

This work presents a lightweight PV module architecture (6 kg/m 2) able to withstand the harshest IEC aging tests, which can be fully manufactured in a PV laminator in less than 30 min. The developed module architecture is based on a composite sandwich backsheet and a polymeric frontsheet.

What is a glass-free lightweight PV module?

Module design Our glass-free lightweight PV modules are composed of two main components: (i) the composite backsheet (skins / sandwich adhesive / core) and (ii) the frontsheet (encapsulant foil / solar cells / polymeric frontsheet).

What is a crystalline silicon PV module?

The majority of today’s crystalline silicon (c-Si) PV modules are manufactured in accordance with a glass-backsheet (GBS) module lay-up: 3.2–4mm glass at the front and a polymer-based insulating backsheet (Fig. 1(a)). An aluminium frame is applied around the module to increase mechanical stability.
