“…For the samples where the ECA was applied to the full length of the busbar area, the cross-section can schematically be depicted as in Fig.1. The ECA that was used was Dow Corning ® PV-5802 Electrically Conductive Adhesive, which is a silicone-based ECA, specifically developed for crystalline silicon photovoltaic module assembly [10]. PV-5802 is a printable paste that cures into a highly conductive (2 × 10 -4 cm) yet soft and elastic solid.…”

Attaching interconnection ribbons to solar cells using electrically conductive adhesives is an attractive alternative to soldering, particularly if it can be achieved on cells without busbars. We report on ribbon bonding tests on busbarless PERC cells using a silicone-based electrically conductive adhesive, comparing the results with those of soldered control samples. The ribbonbonded samples lead to somewhat lower performance, but promising results have nevertheless been obtained that indicate that equivalent performance could be reached with better process control. Proof-of-concepts of innovative structures combining electrically conductive adhesives and non-conductive adhesives are demonstrated, with the potential to yield high fill factors, moderate material consumption and easier application.

“…The connection to the cells is then achieved either via laser welding or electrically conductive adhesives. Also here, compatibility between the conductive backsheet, the ECA and the encapsulant has to be ensured [50,51].…”

In the last decade and longer, photovoltaic module manufacturers have experienced a rapidly growing market along with a dramatic decrease in module prices. Such cost pressures have resulted in a drive to develop and implement new module designs, which either increase performance and/or lifetime of the modules or decrease the cost to produce them. In this paper, the main motivations and benefits but also challenges for material innovations will be discussed. Many of these innovations include the use of new and novel materials in place of more conventional materials or designs. As a result, modules are being produced and sold without a long-term understanding about the performance and reliability of these new materials. This has lead to unexpected new failure mechanisms occuring few years after deployment, such as Potential Induced Degradation or backsheet cracking. None of these failure modes have been detected after the back then common single stress tests. New accelerated test approaches are based on a combination or sequence of multiple stressors that better reflect outdoor conditions. That allows for identification of new degradation modes linked to new module materials or module designs.
