  • The key take-away from the presentation will be this: Traditional photovoltaic technologies severely limit design options. The next generation of flexible products, from companies such as Ascent, enable a wide variety of innovative solar solutions.The value proposition for flexible technologies (next slide)
  • First Gen:Modern silicon solar cell demonstrated by Bell Labs in 1954Second Gen: Thin film solar technologies developing in the late 60’sThird Gen: The next generation of organic and dye sensitized technologies are, for the most part, not yet ready for commercialization
  • Monolithic integration is an in situ process for creating cell units from the photovoltaic material
  • worldwide mobile communications industry
