“…With fast cure and ultra-fast cure types, the crosslinking time was reduced down to 10 min [14][15][16][17]. Alternatively, also thermoplastic encapsulants have been developed, where no crosslinking is needed and the total lamination time was reduced to 10 min [18].…”

“…Many developments aim at improving or better matching the optical properties of the components allowing an increased number of photons to reach the solar cells. Encapsulant films with new additive formulations allow for transparency in the UV region of the incoming light, resulting in an increased power output of up to 0.5% [18,22,23]. Similar effects can be achieved using highly reflective backsheets that act as a diffuse mirror and lead to backscattering of light to the cells [13,24].…”

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.
