EVA and glass size of photovoltaic modules

How can encapsulant architecture improve the PV module output?

We improve the PV module output by the use of a novel encapsulant architecture. We change the front EVA by an encapsulant with a low ultraviolet cut-off. We use a white EVA on the back with the aim to increase the reflection of light. A power increment of 5.16 W has been measured on new encapsulant real size PV modules.

Can Eva be used in glass-glass structures?

The use of EVA in glass-glass structures is in principle discouraged, as a bioproduct of its photo-degradation is acetic-acid, which cannot be released outside the module– as in the case of glass/foil structures – potentially leading to several degradation modes. In particular, the work focuses on the effect of non-optimal EVA storage conditions.

What is a real size PV module?

The seven real size PV modules have been processed in an automatic-industrial line using PV silicon solar cells with a power range equal to [4.425–4.450) W without any change in the standard process conditions.

What encapsulant configurations are used for PV module output power?

The PV module output power per encapsulant configuration is analysed in this section. With this aim, real size PV modules with the three following encapsulant designs have been fabricated: HUV-EVA@HUV-EVA (one PV module), LUV-EVA@HUV-EVA (three) and LUV-EVA@WhiteEVA (three).

Which is better Eva or PVB encapsulation?

The experimental results of thin film photovoltaic module encapsulation indicate that the optical properties of PVB is better than EVA, the adhesion of PVB to photovoltaic cell is better than EVA, while the crosslinked EVA adhered more firmly to glass substrate.

How many watts per fabricated photovoltaic module is Luv-Eva encapsulant?

Regarding LUV-EVA@HUV-EVA encapsulant design, it leads to a maximum P mp increment equal to 3.79 W per fabricated photovoltaic module, while the measured maximum P mp increment for LUV-EVA@White-EVA laminated devices is equal to 5.16 W.
