• "NY Industries, the new thick-film circuit system uses a specially formed conductive paste on heat-resistant substrates such as polyimide and PEN."
• "The actual ones that have been built and (unsuccessfully) flown have all had a polyimide film basis (Kapton or Mylar) because it is a more robust material per mass unit."
• "Ultimately, the ability to deposit thin film PV (amorphous SI, CIGS, CdTe, or hybrid cells) on polymer substrates by reel to reel manufacturing (higher tech version of mylar potato chip bags or flexible polyimide computer peripheral cables) would be expected to be significantly less expensive per watt than silicon, but neither technology is static. —"
