Photovoltaic hollow laminated glass components

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 .

Can SLS glass be used in PV modules?

SLS glass is ubiquitous for architectural and mobility applications; however, in terms of its application in PV modules, there remains room for improvement. In the current paper, we have reviewed the state of the art and conclude that improvements to PV modules can be made by optimizing the cover glass composition.

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.

Why is glass front sheet important for PV modules?

In addition to optical and environmental performance, the mechanical performance of PV modules is also of vital importance, and with the glass front sheet constituting a high proportion of the mass of PV modules, it also impacts on mechanical properties of the PV module composite.

Is polyvinyl butyral a good encapsulant material for GG lamination?

The rapid development of the PV market during the last few years has caused a substantial expansion of the encapsulant material market for photovoltaic applications [15–17]. For GG lamination, polyvinyl butyral (PVB) is a well-known thermoplastic (non-cross-linked) encapsulant.

Which encapsulant is best for a PV module?

The most popular encapsulant for this PV module design has long been (and still is) the copolymer ethylene vinyl acetate (EVA). This type of module has been operational in the field for over 30 years, and several failures have been discovered, observed and investigated [1–3].
