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.
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.
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.
What are the requirements for PV module encapsulants?
The optical gain due to optical coupling becomes less relevant for a cell with an efficient light-trapping texture and ARC. The requirements for PV module encapsulants in terms of optimizing module efficiency can be divided into five categories: electric yield, electrical safety, reliability, module processing and cost.
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 .
