Conversion efficiency of double-sided double-glass modules

What is double glass PV module?

Double glass PV module is known as the ultimate solution for the module encapsulation technique. Although double glass modules have many advantages, they are not yet widely used in photovoltaic power plants, for which one important reason is the large power loss due to the transmission of light in the cell gap region.

Why is white double glass PV module more powerful than transparent?

Due to the high reflectance of white EVA, the power of white double glass module is higher than that of transparent double glass module by 2-4%. Double glass PV modules is an area of significant investigation by many companies and institutes in recent years, for example Dupont, Trina, Apollon, SERIS, MIT, Meyer Burger and Talesun.

What is a double glass module?

Double glass module contains two sheets of glass, whereby the back sheet is made of heat strengthened (semi-tempered) glass to substitute the traditional polymer backsheet. With * Corresponding author. Tel.: +86 13776101913; fax: +86 51268961413.

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.

What is the maximum deformation of a double glass module?

The maximum deformation of long side is tested according to the mechancial load of +5400 Pa for DH1000h, and -5400 Pa for DH2000h. Test result is that double glass module has no problems such as bubbles and delamination after tested under the condition of distortion +DH2000h, and the power loss is 2%.

Are double glass PV modules safe?

Double glass PV modules is an area of significant investigation by many companies and institutes in recent years, for example Dupont, Trina, Apollon, SERIS, MIT, Meyer Burger and Talesun. According to the literature, double glass also has some potential risks besides the abovementioned advantages.
