At the heart of the Cougar™ Platform is the Innovalight™ Silicon Ink. The proprietary material is comprised of silicon nano-particles dispersed in an environmentally friendly blend of chemicals. The result of over 100 engineering-years of ink development, Innovalight has optimized silicon particle size and dopant concentration to maximize the conversion efficiency of the Cougar Platform. Additionally, the material was formulated to be compatible with low-cost industry standard screen printers – the same tool cell manufacturers use for printing metal contacts.
To meet the demand of the Cougar Platform, Innovalight is planning to ramp Silicon Ink production to support over 1,000 MW of Cougar Cells by the end of 2010.
With the formulation of Innovalight Silicon Ink for the Cougar Platform commercialized, Innovalight is now altering the material properties for use with other high efficiency screen printer based platforms in line with Innovalight’s roadmap. In addition to altering the material for novel solar cell designs, the material can also be modified for use with a variety of printing equipment. In fact, a lower viscosity material has been developed for use with inkjet printing equipment.
