Dow Adhesives Offers More Sustainable Solutions for New Photovoltaic and Solar Energy Backsheet Materials

Published on 2009-09-28. Author : SpecialChem

PHILADELPHIA -- Dow Adhesives and Functional Polymers, part of The Dow Chemical Company, participated in the upcoming Photovoltaic Solar Energy Exhibition in Hamburg, Germany. The Company anticipated intense interest in its high-performance adhesives that meet the fast-evolving requirements for newer backsheet applications. and displayd their Adcote™ adhesives and provided attendees with results of work on solventless adhesives for backsheet applications. Dow is a leading global supplier of adhesives for photovoltaics and a pioneer in environmentally advanced technologies. Dow looks forward to discussing its unique contributions including our adhesives' unparalleled performance on newer backsheet substrates, as well as game-changing innovations in materials such as liquid encapsulants for solar cells." Dow dovetails its services and products to fit this exceptionally dynamic industry devoted to harnessing a seemingly limitless energy source: the sun, which sends more energy in one hour than is used annually across the globe.

The PV industry has experienced strong growth in recent years, as it expands its manufacturing base to new regions and continuously implements new technology. For example, manufacturers responded to recent PVF backsheet film shortages by immediately adopting new lamination structures. While such substrates can be difficult to adhere, advanced adhesives such as Adcote, which has proven durability in solar energy applications, was found to offer sustainable features essential to long-term backsheet success: extended durability, resistance to adverse weather conditions, strong bonds on a wide range of challenging substrates, plus flexibility for extreme temperature changes and lightfastness. The company also plans to offer a high-performance 100 percent solids, solventless adhesive option soon, further advancing the environmental performance of solar modules.

Dow commits substantial investment to the entire PV value chain, expecting broad governmental incentives like renewable energy targets, rebate programs, tax credits, sustainable building regulations and feed-in tariffs to boost the already exploding PV and solar energy markets. The Company participates in every part of these markets, developing materials for backsheets, films, solar cells and panels. This involvement, explains Sethuram, is crucial for grid-connected photovoltaic customers as well as for off-grid electricity producers in developing countries. Solar technology today operates in 81 countries, yet two billion people still lack electrical access and PV technology is the least expensive option for most.

"We're continuously innovating to help customers improve conversion efficiencies, reduce cost per watt of electricity, achieve grid parity and extend solar module longevity," said Edward C. Greer, business development and commercialization manager for Dow Emerging Technologies. "We look forward to discussing some of our exciting R&D efforts like a revolutionary liquid encapsulant system to seal and protect PV systems."

Dow offers resources like timely on-site assistance anywhere in the world, and the Company's pilot coaters help customers efficiently build, test and scale up new lamination processes. Sethuram notes that such resources also evaluate cost-saving measures that the industry is exploring. The company is planning to meet high PV demand in Asia with its new Shanghai Dow Center. China has one of the largest PV manufacturing concentrations in the world and Japan is among the top three countries for installed PV capacity.
