Which cover material should be used for PV modules?

Currently, 3-mm-thick glass is the predominant cover material for PV modules, accounting for 10%–25% of the total cost. Here, we review the state-of-the-art of cover glasses for PV modules and present our recent results for improvement of the glass.

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.

How does GG design affect PV module reliability?

This decrease in water vapour ingress has a direct positive impact on PV module reliability compared with that for a standard GBS lay-up. Recent developments of thin, 2mm tempered glass have made GG design a more competitive solution, compared with 3 or 4mm GG modules (heavyweight) or standard GBS modules.

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 .

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 is thermal toughening of PV cover glass?

Thermal toughening of PV cover glass is the most conventional route to meet the standard IEC 61215 on impact resistance that is aimed to simulate hailstorms.
