What type of bonding is required for PV application?

For PV application, bonding is required between organic (encapsulant) and inorganic (glass, cell, metallization) surfaces.

Why do PV modules have poor adhesion bonds?

Moreover, extended lamination duration, which can cause degradation of chemical additives may also lead to poor adhesion bonds between module layers . During the manufacturing process, uneven geometries in a PV module structure due to height differences between the busbar and silicon wafer also pave way for the initiation of delamination.

Are double-glass PV modules durable?

Double-glass PV modules are emerging as a technology which can deliver excellent performance and excellent durability at a competitive cost. In this paper a glass–glass module technology that uses liquid silicone encapsulation is described. The combination of the glass–glass structure and silicone is shown to lead to exceptional durability.

What is a crystalline silicon PV module?

The majority of today’s crystalline silicon (c-Si) PV modules are manufactured in accordance with a glass-backsheet (GBS) module lay-up: 3.2–4mm glass at the front and a polymer-based insulating backsheet (Fig. 1(a)). An aluminium frame is applied around the module to increase mechanical stability.

Can SLS glass be used in PV modules?

SLS glass is ubiquitous for architectural and mobility applications; however, in terms of its application in PV modules, there remains room for improvement. In the current paper, we have reviewed the state of the art and conclude that improvements to PV modules can be made by optimizing the cover glass composition.

How does UV radiation affect PV module adhesion?

Critical debond energy and different adhesion degradation mechanism at front-side of PV module . Exposure to UV radiation under operating conditions can significantly affect the adhesion of polymer layers in the PV modules.
