Following a successful year in 2010, Saint-Gobain Solar, a leading manufacturer of sustainable materials and engineered renewable energy solutions, is on track for an even brighter 2011. The group is bringing new levels of production efficiency and cost savings to photovoltaic module manufacturing processes with its innovative SolarBond™ products.
As the solar market continues to grow, module manufacturers are increasingly aware of the importance of innovative production components to enhance their production processes. Saint-Gobain Solar’s SolarBond™ products – including the new SolarBond™ Frame Sealant and SolarBond™ Frame Tapes – are enabling manufacturers to innovate their production processes and achieve great efficiencies and cost-savings.
Specifically, module framing is one such process that has benefited from the cutting-edge SolarBond™ technologies. The traditional silicone methods used to seal photovoltaic modules lead to significant material waste as well as extensive cleaning time as excess product flows onto the module’s surface after the insertion of the photovoltaic laminate into the frame.
With SolarBond™ Frame Sealant, a new-generation pumpable sealant, Saint-Gobain Solar allows solar module manufacturers to significantly improve performance, while reducing overall production costs. The sealant consists of a foamable, single component reactive thermosetting compound that allows an optimum cavity fill to be achieved without any overflow, reducing cleaning time and eliminating material waste.
In addition, because the sealant is warm when applied, it takes significantly less time to set, and achieves high bonding strength immediately after contact with the glass, backsheet and frame. Instant adhesion in the framing process ensures a consistent level of quality and leads to increased productivity and shortened production cycles. A long-term, weather-resistant bond also assures durability of the final product.
The technology also uses a unique, automated dispensing solution for the framing process, leading to enhanced operational safety and increased capacity to meet growing market demand.
To further enhance the productivity of their framing processes and the performance of solar modules, manufacturers utilize SolarBond™ Frame Tapes. Offering cost-effectiveness, easy application and durability in the solar module framing process compared to alternative products, the tapes are used for perimeter sealing of the PV laminate to the aluminium frame. With instant bonding, manufacturers can handle the module immediately after framing, resulting in increased production efficiency.The SolarBond™ Frame Tapes are UL listed and offer performance to IEC (International Electrotechnical Commission) conditions for adhesion strength, weatherability and durability as confirmed by TÜV Rheinland, a respected independent testing and assessment service.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
