PV module is a packaged and protected system in which multiple PV cells are connected to deliver the electric power. Generally, PV cells in a PV module may be crystalline, semi-crystalline, or amorphous and they are safely packaged in multiple protective layers including front cover, encapsulate, and back sheet.
Ethylene vinyl acetate EVA, a copolymer of ethylene and vinyl acetate is the predominating material of choice for manufacturing the encapsulate film since the early eighties, and nearly 80% of PV modules are encapsulated with EVA film [4, 13, 29].
Encapsulation of PV modules is one among the multiple ways to mitigate these stability issues and it plays an important role in the enhancement of the device lifetime by providing a barrier structure to restrict the penetration of oxygen and moisture.
Generally, the encapsulate is a polymeric film which plays a critical role in avoiding environmental degradation or improving the stability of PV cells through the formation of a cross-linking network structure during the lamination of the PV module.
Frame: the majority of PV modules are fitted with an anodized aluminum frame, which hugs the front cover at the top and the back sheet at the bottom. Framed PV modules are better protected than frameless modules during transportation. Fig. 1. Components of a PV module (Reproduced with permission from Ref. . Copyright 2017, Elsevier Ltd). 3.
During the long time operation at outdoor conditions, PV cells experience significant morphological and structural changes, optical absorption decay, and impairment of the optoelectronic properties, which adversely affect the performance of the PV module [7, 8].

Photovoltaic cell module and its packaging. November 12, 2021 December 21, 2021 admin. The output voltage of a single monocrystalline silicon photovoltaic cell is only about 0.5V under standard illuminance (1000W/m²), and the output power of a common single cell is generally about 1W. In addition to the small capacity of the single battery, its mechanical …
We demonstrate that with the proper module packaging (i.e. a glass/glass structure with edge sealant), EVA can be used as an encapsulant material for SHJ solar cells. PID can be completely prevented even when subjected to extended tests (e.g. eight times the 96 h of test duration foreseen in the IEC Technical Specification for c-Si modules).
The invention aims to provide an encapsulating layer, a photovoltaic cell serial and a photovoltaic module manufacturing method, so as to reduce the extrusion force of a rubber plate on...
