Honeywell has launched its third-generation laminate film, ‘PowerShield’ 3W, which is designed to protect PV modules from harsh environments while helping them maintain power output over their 25-year life-spans. Problem PV module manufacturers require cost effective and reliable protection for cells and circuitry, while meeting the cost reduction challenges. Solution PowerShield 3W is claimed to be a cost-effective backsheet preventing moisture from entering the module and keeping electrical charges within the module. These features help the module retain maximum power output while maintaining electrical safety. The new laminate is bound by a proprietary adhesive specifically designed for photovoltaic applications. The adhesive helps make the laminate the most durable backsheet available from Honeywell to date. Independent photovoltaic-industry laboratory tests were said to show that PowerShield 3W can withstand more than 3,000 hours of accelerating aging exposure at 85°C (185°F) and 85 percent relative humidity without losing structural integrity. Applications PV module encapsulation. Platform The backsheet’s superior adhesive offers excellent resistance to discoloration due to aging, which helps solar modules retain their appearance and reflectivity. Like all PowerShield backsheets, PowerShield 3W offers high resistance to environmental degradation from sunlight, heat, cold and humidity; strong resistance to acids, bases, solvents, salts and other chemicals; and resistance to excessive moisture infiltration within a module. The Honeywell PowerShield supply chain is said to provide module makers with a single point of contact for every component of their backsheet, helping ensure a reliable supply and quality.

PV storage Publications Photovoltaics International 22nd Edition The period of ‘profitless prosperity’ in the PV industry is finally at an end. Throughout 2013, despite continued economic woes, the PV industry has continued to expand and finally become a global industry. Market forecasts indicating that the sector could reach its next 100GW milestone in just the next two years suggest the industry is on the cusp of another period of strong growth. All the signs confirm this is the case, with utilization rates at their highest level since 2010, companies reporting full order books well into next year and the first tentative announcements of factory capacity expansions making the headlines. Although the really significant capacity expansions that would confirm a fullblooded upswing have yet to materialize, ‘effective capacity’ in 2014 is highly unlikely to meet end-market demand, should forecasts of 45 to 55GW come true. When the next technology and buy cycle occurs is still a moot point but it’s closer than many would have dared to think at the beginning of this year. The 22nd edition of Photovoltaics International will be an indispensible resource as that buy cycle draws nearer. Manufacturing The Solar Future: The 2013 Production Annual In the ever-changing global solar markets, cost reduction and measures to increase cell efficiencies are the key tools available to PV manufacturers to create new opportunities and drive your business to the next level. Manufacturing the Solar Future 2013 is the third in the Photovoltaics International PV Production Annual series, delivering the next instalment of in-depth technical manufacturing information on PV production processes designed to help you gain the competitive edge.
