Conductive polymers have been playing a crucial role and some of the newly launched products in this area have provided a glimpse of the latest development trends. Polymer solar cells have been in the market for years now. These utilize organic compounds to produce electricity from sunlight and are more environmentallyfriendly option and cheaper to produce than traditional silicon-based solar cells. What we are seeing now are the growing number of companies us ing more advanced technologies for powering portable electronics such as mobile phones, laptops and mp3 players. While electronics are on their way to becoming a global necessity, the fact remains that many devices are limited by battery capacity. And wi th growing var iety of functions now being developed for these products, longer battery life will be a primary focus and in this aspect, plastic solar cells will definitely set the standards. Solarmer Energy is developing a plastic solar cell that is expected to achieve 8% efficiency and a lifetime of at least 3 years for portable electronics later this year. The company claims plastic solar cell and plastic solar panel efficiencies at 6.77% and 3.9% respectively. Plastic solar cells can be integrated into bags, sleeves and cases for portable electronics. Portable electronics is the most attractive near-term application for plastic solar cells because of its easy integration combined with the high demand for an alternative or replacement to existing battery technology. The company hopes to capture this niche market with organic thin-film plastic that it claims can convert sunlight into electricity more efficiently at a lower production cost. Efficiency level raised A new record efficiency of 13.4% for Copper- Indium-Gallium-Diselenide solar cells (CIGS) on a plastic substrate produced on an industrial rollto- roll system had been recorded by Solarion AG from Leipzig, Germany. The record cells do not employ anti-reflective coating. The result has been independently verified by the Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg, Germany. Solarion's proprietary ion beam technology for the production of flexible solar cells not only uses less raw materials and energy, but also reaches high conversion efficiencies. This result is not only a world record efficiency for flexible CIGS solar cells manufactured on a plastic substrate in an industrial roll-to-roll coating process, but is also the highest efficiency for any thin film solar cell on a flexible polymer substrate from a roll-to-roll process, regardless of the absorber material. The patented ion beam process for producing the CIGS absorber allows the reduction of process temperature and thus the use of a flexible polymer substrate. The combination of a low-cost polymer substrate, the ion beam technology and a roll-to-roll production process enabled the company to reduce manufacturing costs significantly. The flexibility and high efficiency of these solar cells opens up new large-volume applications. Targeting electronic devices and components Saint-Gobain Performance Plastics has developed its series of Rulon® and Meldin® materials that are now found in a wide variety of electronic devices and in equipment to manufacture electronic components. Integral parts made from Meldin® 7000 series are particularly well-suited for the harsh environments commonly found during the operation of electronic component manufacturing equipment used for processes such as LCD sputtering, PV thin film sputtering, plasma etching, and Plasma Enhanced Chemical Vapor Deposition (PECVD). The Meldin 7001 grade is ideal for these types of applications due to its outstanding dielectric properties, high purity, low out gassing, strong chemical compatibility, and high temperature resistance properties.
