About Use of Yushu Lightweight Photovoltaic Epoxy Board
With the aim of limiting the weight while preserving excellent mechanical stability and durability properties, we propose a new design for lightweight crystalline-silicon (c-Si) PV modules in which the conventional polymer backsheet (or glass) is replaced by a composite sandwich structure, and the frontsheet by a transparent polymer foil.

This work focuses on the development of a lightweight, glass-free photovoltaic (PV) module (6 kg/m 2) composed of a composite sandwich back-structure and a polymeric front layer. Sandwich structures are usually manufactured with a vacuum bag process and thermosetting liquid glues (e.g. epoxy resin).
Four prototypes of lightweight photovoltaic modules for applications in on-grid systems have been designed, developed, manufactured and tested for compliance with relevant IEC standards. Selected, commercially available materials characterized by thermogravimetry, differential scanning calorimetry, dilatometry, scanning electron microscopy and .
Photovoltaic modules were manufactured by vacuum resin infusion process using glass reinforced epoxy composite as encapsulant where the cells are embedded. Incorporation of ultraviolet absorber (UVA) and hindered amine light stabilizer (HALS) additives to the epoxy resin was studied, given their potential to enhance the performance stability of .

6 FAQs about [Use of Yushu Lightweight Photovoltaic Epoxy Board]
Can crystalline-silicon PV modules be lightweight?
With the aim of limiting the weight while preserving excellent mechanical stability and durability properties, we propose a new design for lightweight crystalline-silicon (c-Si) PV modules in which the conventional polymer backsheet (or glass) is replaced by a composite sandwich structure, and the frontsheet by a transparent polymer foil.
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).
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.
How stable are lightweight PV modules based on a polyolefin based sandwich?
Thermo-mechanical and electrical stability of lightweight PV modules based on PO and aluminum core The strongest and most stable composite sandwich structure developed in this study (polyolefin-based sandwich with an aluminum honeycomb core) is selected to produce two-cell modules.
Do light structures of frameless PV modules have refined manufacturing technology?
To sum up, the present paper concerns light structures of frameless PV modules with refined manufacturing technology. As an extension of the small-scale investigations known from the literature, it can be useful for those who design and prepare production of such structures of standard size.
Are lightweight photovoltaic modules IEC compliant?
The results of the prototypes' complete IEC test sequence were presented. Construction details and manufacturing processes were described. Four prototypes of lightweight photovoltaic modules for applications in on-grid systems have been designed, developed, manufactured and tested for compliance with relevant IEC standards.
