Why do PV modules have a glass-glass edge seal?
The edge seal is exposed to UV radiation and different weather conditions during the lifetime of the module. Moisture ingress will degrade the performance of a PV module. An advantage of the glass-glass configuration is that moisture ingress can occur only along the perimeter of the module.
Can edge seal materials be used in photovoltaic applications?
Here, using a Ca film deposited on a glass substrate, we demonstrate the evaluation of edge seal materials in a manner that effectively duplicates their use in a photovoltaic application and compare the results with standard methods for measuring water vapor transport.
Why should we encapsulate thin film PV modules?
Since the lamination process is a well-established technology, lamination in the thin film PV module is also primarily used to reduce the overheard research cost. This creates a void for an innovative technology to encapsulate thin film PV modules.
How thick is a glass – glass PV module?
Then the entire glass – glass structure encompassing the polymers is laminated (Strevel et al., 2013). Modules were assumed to be 1200 mm long and 600 mm wide and the EVA sheet was assumed to be 0.5 mm thick. For cost analysis, thin film PV modules with a double edge seal and varying interlayer laminate are considered.
What are the disadvantages of PVB encapsulants?
The main disadvantage of PVB over other encapsulants is its high susceptibility to hydrolysis, making it a less attractive choice for G/B modules. However, in G/G modules, edge seal materials can effectively restrict water penetration to the module as this can only diffuse from the edges.
Does double edge seal reduce the cost of polymers compared to glass-Eva-glass modules?
Cost analysis indicated that the double edge seal with interlayer laminate of polyolefin or polyethylene significantly reduced the cost of the polymers when compared to glass-EVA-glass modules. Polymer extrusion and injection molding were the processes that can be used for the fabrication of thin film PV modules with the identified materials.
