Double glass component curing

What is dual curing?

The most conventional dual-curing is based on photo-thermal sequential curing, where the main objective is to obtain an intermediate material with tunable properties and a final product with excellent mechanical properties , , .

What is a double glass c-Si PV module?

Recently several double-glass (also called glass–glass or dual-glass modules) c-Si PV modules have been launched on the market, many of them by major PV manufacturers. These modules use a sheet of tempered glass at the rear of the module instead of the conventional polymer-based backsheet. There are several reasons why this structure is appealing.

What is the encapsulation reliability risk of double glass module?

The double glass module is superior to the conventional single glass module, which indicates that the encapsulation reliability risk of double glass module is good without delaminating risk. 90 Jing Tang et al. / Energy Procedia 130 (2017) 87–93 4 J. Tang et al./ Energy Procedia 00 (2017) 000–000 Fig. 3.

How does silicone curing work?

Another glass panel is coated with the encapsulant and is then turned upside down and placed onto the first panel containing the cell matrix. The whole sandwich is then introduced into a laminator, where a vacuum is drawn and the laminate is heated up, thus beginning the silicone curing process.

Why is sequential thermal-photo curing better than dual curing?

With the strategy of sequential thermal-photo curing strategy, higher temperatures during the first stage of thermal curing can affect the reactive groups of the photo-curing process, and the longer thermal curing time loses the advantage of dual curing.

How reliable is Canadian Solar's Dymond double glass module?

Canadian Solar’s Dymond double glass module passed 3 times IEC standard test and IEC 61730-2:2016 multiple combination of limit test and obtained VDE report, which fully indicate high lifetime and high reliability of this double glass module. This paper presents a detailed reliability study of Canadian Solar’s Dymond double glass module.
